I've tried to print this on my Ender 3 a few times now but each time I go to print the holder for the roller, after a certain number of layers the layers get off center but a millimeter or so. As far as I can tell in Cura everything looks fine when going to slice it, but my printer just won't behave on it. It's always in the same spot too that it gets off center, and then it doesn't have any other issues with it for the rest of the print. Can I get some advice for fixing it? It probably wouldn't make the spool unusable, but it looks bad to me.

It's not the fault of the object. You have layer shift.

I can't seem to mount the CR-10 & Ender 3 brace to snap onto my cr-10s frame without it cracking at the right angle on the bottom. An advice on getting this to work? I'm considering switching from PLA to PETG to get that last little bit of flex hold before it snaps down.

I haven't seen this problem before. You could try to file the bit that snaps on until it fits smoothly, you could try sliding it on from the side of the aluminium extrusion, you could try scaling the model up by 2-3% in your slicer and like you said, changing the type of filament you use. Good luck!

If anyone is struggling with the end caps breaking on the roller I made some that fit a 22mm tube/pipe so you don't need to keep printing out the whole roller

Hope you don't mind me editing it a little HugoHuge :)

End caps for filament roller
by Baggi0

Of course I don't mind you editing it, that's what the .STEP files are for! Looks good, I'll link it to the people who have trouble with the posts on the roller in the future.

This thing is great! Very strong....exactly what I needed. I will say that if you print the threaded bracket for the Ender printers, you may not need infill around the threads...that infill is a pain to get out of there! Great print! Thanks for all of the updates too!

No problem! I'm glad you like it!

I apologize if this has been answered before.
Is there a remix on the holder for a Prusa bear upgrade?
Thank you.

No, I dont think there is a direct remix for the Bear upgrade, but I think this might be what you are looking for: https://www.thingiverse.com/thing:3442347.

Have a nice day!

Filament Spool Holder for Artillery Sidewinder X-1, Cr-10, Tevo Tornado, 2020 & 2040 Extrusions with filament sensor.
by Desima

Hey HugoHuge.
At the moment I'm working at a big remix of your The Filler.
Look what I've done to today!
Would it be possible to send me all your mounts as a step or as f3d?
That would be really nice
Greetings ^^

Of course! I'll be putting the .STEP files in the Thing Files asap. Your remix looks really good, I'm curious to see what it looks like when it is finished!

How about a mount that fits on the side of a Bear upgrade for a Prusa i3 (2040 v slot) so that we can mount our spool holder onto that? PLEASE?!?!?!?

Looks like there is already a remix like this: https://www.thingiverse.com/thing:3482452. I've stopped working on this model, so if you want something different, you'd have to remix it yourself. I'll be placing the .STEP files in the Thing Files soon. Good luck!

by MachBar

Just finished printing and assembling this for my ender 3. Works fantastic and helps my spools of PLA run smoother. Thank you for this :)

i cant print 3DPNFilHoldRoller, what oritantion did u print ?

Standing straight up vertically with supports only touching the bed. I think I also used rafts as bed adhesion.

2 times failed at the top add infil trying third now lol

I used 20 or 30% infill to give it more rigidity and a resolution of 0.16 I believe.

I really like Filler on my free-standing CR-10s, but I also have one printer in an enclosure, and wanted to use the Filler spindles. I've made a simple cradle for setting on the enclosure.

Dual Cradle for Filler Filament Holder

Cool, looks good!

Can you add a clamp version to the mount side. Very impressive modular design. Love it!

I'm sorry, but I've stopped working on this model. I'll be putting the .STEP files in the Thing Files so if you want you can edit it yourself. Good luck!

Hi! The diameter of the hole in my spools was smaller than the "Hold guide" part of this print, so they didn't fit. I've modified this part so it fits spools with an inner diameter up to 4.5cm (1.77 inch), here's the remix: https://www.thingiverse.com/thing:3429902

Hold Guide modified for spools with a smaller hole
by tincat

Cool, looks good!

Comments deleted.

If you mean width, it can take about 8.5 cm at max.

Wow, this works really well. I tried to print the spindle on it's side but it does better as provided on end with support from build plate.
Thank you for sharing this.

Cool! I'm glad it works for you!

how long spool can this hold take? can it take 9,4 cm spool?

No, the max width is 8.5 cm. I'll be putting .STEP files in the Thing Files asap!

Hello! I was wanting to remix this to fit a different size bearing that I already have several of. Would you be willing to share the 3D files for the parts the bearings touch? Thanks!

Very good coil holder, I recommend. Nice job, thank you.

Thanks! I appreciate the compliment!

Over spin is often caused from having a high amount of static friction/tension that needs to be over come before the spool will move. Once the friction is over come all the force is released at once.

Try reducing the tension required to spin the spool in the first place:
1) place the spool closer to the extruder (shorten the length of filament between spool and extruder)
2) any sharp turns between the spool and extruder
3) avoid having the filament rub up against any surfaces. If it does rub up against corners or guides try placing them closer to the extruder and away from the spool.
4) It would be a pain but you could run a bowden tube between the spool and the extruder

If none of these are an option... maybe try taking the bearings off or using poor bearings.

I notice you have the spool on the shelf above the printer. I used to use the same configuration. Now I just have it next to my printer using command strips. You can check it out in my make photo I posted.

Hi. Great design. Will post a make later.

I was wondering if it is possible to put the slot for the guide on the mount/brace for the Prusa i3 Mk3 on the other side, so I can put two holders side-by-side. A bit like the stock holder on the Mk3 is.

Or one brace, that can hold two guides and rollers. That would be even better.

I'm very bad at 3d designing, otherwise I would give it a try myself.

I'm sorry, but I stopped working on this model. It has pretty much everything people could want. In your case, what I'd suggest is mirroring it in Cura or your preferred slicer so it flips the side the slot is on, as well as the place it attaches to the frame. This will probably solve your problems.

Have a nice day!

No problem. I tried it myself and I succeeded... ;-) I'll upload it as a remix.

Second time I print the center roll, any tips on how to fix this? Seems the top and bottom walls are too thin
Using Cura, following the recommended settings.

Note: I am also using the side holder for the Ender3, might make a spacer to extend it so the roll goes a bit further away, still thinking how to fix it :)

I've just finished printing the roller and experienced the same problem that you did. I reprinted it with a top and bottom thickness of 1.6mm instead of the 0.6mm it was set to as standard and it came out perfect. I also set it to have 20% infill to give the top layer something to rest on. (not sure if this is needed)

I'm sure there may be a more elegant way of solving the problem but as I'm still very new to 3d printing I did this and it worked for me.

Comments deleted.

I'd suggest using this remix. It makes the pin and the roller two different pieces to print, so you should't have to use supports :D. Link: https://www.thingiverse.com/thing:3055046

Good luck!

Roller and 2020 brace for Filler - Customizable Filament Holder - hollow with separate pin

Can anyone measure the dimensions of the spool holder with stand real quick?
I'm in store and there is a slick box I would love to put over the spool to keep moisture out lol

Currently printing the second roller for a second one of these. I did however have to make a new filler brace for the 2x2 shelf that I use for my spools. I will upload the remix file to Thingiverse soon.

I just sliced the spool roller in Cura 3.6 and see a split up the entire length of the roller in the layer view. Is this not a complete cylinder? Is this split intentional, or does it print completely? I want to make sure before I print it. Thanks for the great design!

Weird, that shouldn't be there, I don't have that problem myself. Maybe you could try slicing it with the recommended settings? If that doesn't work either, you could try downloading it again, using a different version of Cura or using Meshmixer to repair the mesh.

Interesting. I resliced it and it is still showing up in the layer view. Did your's show up like this? I guess I can give it a go.

No, I never had these problems, but from what I can tell it might be your Z Seam Alignment. Maybe try changing it's values, it might help.

Thanks for your help! I am still pretty new and had the z seam alignment set to: sharpest corner. I changed it to random and it went away. Maybe this can help other noobs!

Great! Experience will come with time, I've had these things the past years as well so I know how it can be.

I'm glad it helped, good luck!

Thanks again. I really appreciate it! I will post a make when I finally get it made. Have a great day.

Does the Creality Nut need supports on the inside for the threads?

I just installed your design on my ender 3 and it works perfectly.
There is virtually no resistance between my spool and extruder (with the help of the 2020 / Ender 3 Filament Guide).
It made a positive impact on my prints immediately!
Great design!
100% recommend

Great to hear! That's exactly what it's meant to do!

My center diameter of my spools are 55mm will this work?

Thanks

Yes. It works great on my spools with 50 and 70mm, so 55mm should be fine.

Do you think it would be possible to create some kind of wall mount like this for your roller and guide ?
https://www.thingiverse.com/thing:2348220
like maybe the guide would slide down onto one side of the mount and the other side would support the guide up.

Yet another Spool Wall Mount
by gkol

I think this would actually work pretty well if you just made the roller with the skateboard bearings. the only issue is the skateboard bearings are 22mm in diameter and that says max 20. perhaps just widen it a bit in cura?

Very cool design. Just a suggestion, If you have a version where you replace the roller with PVC tube and print 2 plugs the mount on each end of the tube and still use the bearings you could forego printing the roller altogether. PVC has more than enough strength to handle the job.

Someone already made a remix like that for a metal tube, you could remix that for the thickness of your PVC tube. This is the remix: https://www.thingiverse.com/thing:3070732

Filament Roller End caps for 22mm Tube
by Cargy

Yup! That's the idea, just with readily available PVC instead of closet rod.

Thanks for the reply.

In the notes you said that you added a mount for 2020 extrusion but I don't see one labeled for 2020 in the parts list. Which mount is for attaching to 2020 extrusions?

Yes, it's the CR-10/Ender file. I renamed it after I rendered it and made the file to 2020 because other 3D-printers with 2020 frames can use it, but that's the file I'm referring to. I'll add that in the notes. Thanks!

So I printed out all my parts for my Ender 3 but I'm using this ount that puts the spool off to the side of the base
https://www.thingiverse.com/thing:2967567

Unfortunately with the Ender 3 mount it puts the spool right in the way of the Zmotor assempbly. I had to move the spool back up top for now until I can figure out what else I can do to make the feed more direct from the side. Perhaps I'll screw it to the desk.

Also the screw for the Ender 3 shapes is REALLY tight.

Ender-3 Side Spool Mount

It's also possible that you have some elephant foot-ing, where the first layer or three are bulged out slightly due to squish, weight, and bed heat. This will majorly impact nuts and bolts that you print that start at the bed. I use a deburring tool to shave the first couple layer widths down after the print's done.

I made the Ender 3 version with the metal brace in mind while it is on top of the frame, so I didn't know this was a problem.
If the Ender 3 screw is really tight you could try putting some graphite powder lubricant in between for it to go a little smoother.

There is a great tip at this make: https://www.thingiverse.com/make:522807
When you add 5% grid infill when slicing the roller you get a nice X through the center for extra strength.

Filler - The Customizable Filament Holder that fills your printer!
by Sw0rd

Agreed! Sw0rd helped me with designing the Ender 3 mount, so he knows what he's talking about!

Would it be possible for you to make one for spools with 32mm diameters? Spools from AMZ3D doesn't fit on this.

I know it would probably be a challenge, but I think you could make it shorter so the 1kg won't be on the very end of the spool holder.

I'm sorry to say I won't be adding/changing any current files. It has pretty much every basic file, and if you'd like different versions, there are a lot of fantastic remixes. This one might be what you're looking for: https://www.thingiverse.com/thing:3091737. Shortening this one should't be a problem as well.

Have a great day!

Slim Spool Holder for use with "Filler" Filament holder - with added lip

Thank you! :)

Thank you for this design! It is the best functional mod that I have printed! No more getting up to check the spool. I would have liked it to have been a bit shorter but this is awesome. Thank you again!

Great to hear! Unfortunately, I won't be modifying it anymore, so I won't make it shorter, but I bet someone is willing to do so, so there might be a remix out one day!

Have a great day

I love your design !!
I have made an alteration to it though, so that the rolls can be held at an angle, because I wanted to mount this in the rear corner of my enclosure.
I will include the stl file here.
(But if you would prefer that I don't, please let me know, and I will remove it.)
Thanks for your design !!
I love it, and I consider it the best one that I have seen, on any site !!

Majix007, can you please make a photo how exactly it is installed? Thank you!

Here is a photo of it installed, both with the roller and without.
There is usually a plexi-glass door in place of the white board on the left.
You have to install it far enough away from the corner to be able to move a roll on and off.
Or you can slide up the roller and detach it from the wall mount, put on a new roll, and then slide them back down together.
It's your choice.
I prefer to just slide the rolls on and off.

Thank you very much!

You could also post it as a remix! That'll probably get a lot more attention that posting it here as a loose file. It looks cool though, I imagine it can be very useful.

I'm glad you like it, have a nice day!

Hello,
Which files should i use for creality cr10 please ?
Thanks

Depends, If you want to use the metal brace, use the Ender 3 version, if not, use the 2020 version.

Great design! Would it be possible to get one for hanging on a closet rod?

I'm glad you like it!
I think it would be possible to make one for a closet rod, except if it is round. Also, there are a lot of closet rods, so I think it is best if you make one yourself. I've placed the .STEP files in the Thing Files, so you could make one without too much hassle.

Good luck!

Really great concept. Respect! That saves me a lot of work! I will upload photos as soon as the system is finished. Thanks and greetings from Germany

Cool, I'm curious to see how it turned out!

Lo voy a hacer, gracias...

No hay problema

Inspired design. Keep up the promising work.

Maybe I am doing this wrong but it seems to be facing the wrong directiong if I mount it to my Ender 3, its facing the wrong direction because the spool goes the other direction and is fed through the side, its not a top down setup. Did I print the wrong parts? I used the Creality C-10 Ender mount.

No, you're not doing it wrong, it is supposed to be like that. The spool should fit on like this (https://www.thingiverse.com/make:530979) but is seems like that wont work because of your tool holder. If you want it to be in the other direction you can use Wile28's remix (https://www.thingiverse.com/thing:3160525), this one also let's you use 2 spools at the same time.

I also see you aren't using the Filler mount for the metal brace provided with the Ender 3, might want to try it out ;).

Ender 3, CR-10 Spool holder
by Wile28
Filler - The Customizable Filament Holder that fills your printer!

Maomaobadmonkey is correct. You cannot use the CR-10 Ender version with the Ender 3...it is the wrong orientation. It has nothing to do with the tool holder. The Wile28 remix would work, but the better option would be to use the Creality Bolt and Creality Nut files along with the metal brace provided with the Ender 3. Thank you for creating this Thing. I look forward to printing it as soon as I get some bearings.

would gear bearings work in this?

What do you mean with Gear Bearings? Filler is made to work with 608 bearings, you can look up the measurements for it to see if your bearings will work. The 608 bearings are available here: https://amzn.to/2LQmdNB, here: https://amzn.to/2LOilNd (For US) and in any local skate shop.

I think it could be done, but you'd have to print a Gear Bearing with the dimensions of a 608 bearing (Thickness = 7mm, Inner diameter = 8mm & Outer diameter = 22mm) which would be very small, and you'd need a printer that can print in great detail. If you want to use it, I suggest using a metal 3D printing service, but that'd cost a lot of money, so it would be a better value for your money if you bought some bearings from Amazon or something like that.

i'll try thanks for the demensions

Has anyone made a stand for this? I want to put it on top my ikea lack tables.

I have made a stand for it, I just haven't posted it yet because I'm not fully satisfied with it, but it does work. If you'd like, I can post is when I have time.
EDIT: Someone has made a remix for the brace so it fits on a LACK table.

Hello,

It's great but a bit long, would it be possible to make a smaller version?

I'm sorry, but I don't have the time to make changes myself. You could, if you want to, download the stl, open Tinkercad and change it yourself :)

Hey, this is awesome, and finishes my Ender 3 upgrading! Thank you. I've made a few parts myself, but the spool holder was one of my final projects, and this is better than I ever could have done.

I'm glad you like it!

Comments deleted.

Great design. I no longer hear screeching sound from the spool trying to spin from the default Ender3 spool holder.

Great! That's good to hear!

Nice work. Do you know if and how can I use it for a top mount spool?

I don't fully understand what you mean with 'Top mount'. Right now I don't think so.

Hey, i like your design and would like to print the version the Anet A8 but unfortunately the part is too big and wont fit the printing area... Really sad :(

CURA said it was too big even at an angle. I then realized that I had it set to print a brim. When I changed it to skirt CURA changed its mind. I have not printed it yet.

It should fit if you turn in so it's diagonally on the heated bed. Otherwise you could try to cut it in half in meshmixer or tinkercad and glue it together with something like CA glue. I'm half you like it and good luck with printing!

Nice one.
Would be great if you could add a mount for 30x30 aluminium extrusions.

I hope I'll be able to do it soon, but school started and takes up most of my free time. Maybe you can design one yourself if possible, since I added the .step file. I'm glad you like it though!

Nice design!
Any way to get the source for the brace?.
I need to adapt it to my custom printer that has a frame made on steel, 3mm thick and 35mm high.
Thanks in advance.

I will post it when I get home later this week. Maybe send me a direct message so I won't forget!

Wow! So good! Easy to print. Great clearances! Being able to change out the mounting base is awesome too!

Thank you! It's great that you like it!

Even better than I first realized! I have very little room on the right side of my printer. So little room that I cannot take my spool off the holder. No Problem! The holder easily lifts out of the wall mount. Crisis avoided.

I just had a spool manage to work itself off this holder tonight. I need to make sure i'm not drooping toward the back. A straight edge on the roller might help keep the spool on vs the tapered edge.

I will try to fix it as soon as possible, though I don't have a lot of free time on my hands since school just started.

I love the design. I think short term I'll try to bend the metal holder to make it lean more toward the front of the printer. This little piece of metal is tougher than it looks.

I added a threaded end to the roller guide with a matching nut that should fit nicely on the Creality Ender 3, CR10 with the original metal bracket without needing to print the adapter. This should reduce time and print filament.

This one might work out much better than the one that Hugo put up. With his shape it gets in teh way of the Z motor when using the side-mount.

https://www.thingiverse.com/thing:2967567

I'll try it! Did you add this as a remix?

Ender-3 Side Spool Mount

Very useful Ender-3 mod. Thanks!

Cool! Maybe you could post it as a remix so it can get some likes and grow a following of it's own!

Can you please add a 2020 / 3030 mount that is similar to the wall mount?

I'm sorry, school started again so I don't have much if any time to work on this. Thanks for asking though, I will keep it in mind!

this is a Massive upgrade, I'll be sticking it on the ender xxMDK

Thanks! I'm glad you like it :)

the one in the box is good & really tough, but too big. I'm trying to lose weight (on my ender) for slight speed accuracy imp & easier lugging ;o) Love this rolly roller :oD sbrillaint! XxX

This is the nicest looking roller I've seen, thanks for sharing!

Do you have any plans to add a freestanding variant with two rollers and its own printed base? A bit like this.

No stress either way, top work.

Ball Bearing Filament Holder
by Chrlee

I was working on one but kind of neglected it, but I will try to finish it soon!

Dude no worries at all. We are a bunch of choosing beggars!

Any chance you could make a 606 bearing sized variant? That might also help with the smaller spools.

I'm afraid that won't work, as I would have to make a lot of changes that would damage the model itself. You might want to remix it yourself, since that might be a better and quicker solution.

Neat design but for the CR10-Ender3 bolt and nut, can I use factory nut ?
Also will 608ZZ bearing fit ?

No, this is not made for the factory nut because, If you print it with the bolt facing upward, you don't need any support on the model itself because the threads are a little bitter, and the nut I made is bigger and easier to tighten.
You can use any type of 608 bearing, because the '608' part identifies the dimensions of the bearing which is the crucial part (being 7 mm thick, 22 mm outer diameter, 8 mm inner diameter), and the letters on the end identify how the balls are protected (ZZ being protected by metal plates on both sides)

How do you print the bolt without support ?

In Cura you'll have to print them individually, but the bolt only needs support touching the build plate, and the nut doesn't need support at all.

Ok thanks, so will print both bolt and nut since I already have the metal rack with Ender 3 :)

Comments deleted.

This looks great! My only suggestion is to remove the pin from one side of the roller and add it back in as a peg. That way you can print it without supports. Edit: I remixed it myself. I also hollowed it out. it'll be 4 perimeter lines at .4mm with no infill for faster printing.

Great addition! Though I wonder how much print time it actually removes from the original. I will link it in the Details if people want to use it :)
EDIT: Would you mind posting it as a make? I'd like to see how it turned out!

I checked my current settings for both objects, and it was only about a 10 min time saving as I have my printer slow down if the per layer time is too short. The material use was 5.5m instead of 7.1m, so there was a slight savings there. Make is added to .. .well, makes. ;)

I also added a medium and short height 2020 brace with a 5mm bolt hole for extra security.

Great design! Just what I needed too!

Cool! I'm glad it works for the Ultimaker!

This is awesome! I had a similar idea but yours is even better. Printed just fine and works perfect for my Prusa! TY again!

Great! I'm glad you like it and it works for you! Would you mind posting it as a Make? I like seeing how other people's prints turned out :)

Just did, with a timelapse :)

Wow, It looks great! The timelapse is awesome! Thanks!

Your original guide was too large for Amaz3d spools, i've uploaded a remix for anyone who runs into the same issues I did.

Good idea! Should help people who want to use spools less 750g!

This is such a clean and useful design!
Been thinking about doing something along these lines, but never got around to actually modeling one. This will save me some time, (and materials!)

Thanks for the awesome work!

Thank you! I really appreciate that! I hope you'll enjoy Filler :D

This is great. I made one similar, but you're is much more refined. The problem I had with mine is that the spool rolls "too well". In fact, I walked out to a roll that had unrolled itself a good bit and was laying on al over the floor lol. Have you had a similar thought? I'd wonder if there is a way to "tighten" it a bit, perhaps some sort of adjustable spring or "brake pad". Thoughts?

ckeck the thing details,,,

UPDATE (26/08/2018)
Added plastic bearing with increased friction. Use this when experiencing problems with normal bearings. You can add some graphite powder lubricant in between the roller and the plastic bearing for better rolling.

or just use 1 normal 608 bearing on one end of the roller and the update bearing at the other end of the roller.

In my experience the roll doesn't unwind by itself, but if you'd like I could make a plastic holder that sits in the spot of the bearings to add a bit of friction. This could help resolve your problem :)

This looks great! Looking to get something more stable than my current tush setup. Is using only one filler recommended, does the difference in diameter between the rolling pin and the spool cause any issues? Should I be looking at finding a way to use two fillers instead? (I saw the gifs, the two filler setup looked smoother, or perhaps I imagined it?)

If you spin the roll on the single Filler fast it is a little wobbly, but when printing using Filler it hardly wobbles at all. You can always use two Fillers, which might be a better idea of you're using a printer that uses a lot of filament at once, like the Lulzbot Taz with the MOARstruder. Otherwise I'd stick with the single Filler set-up.

Great! When I get my Ender 3, this is going up!

I'd love to whip up a little mount for the Monoprice Maker Select/Wanhao Di3. If you'd be willing to share the f3d for just the brace portion that'd make life really easy!

I'm currently working on a CR-10 filament holder that'd work with the Monoprice Maker Select after some minor changes. It uses metal part provided with the printer that has a hole in it, and uses a printed bolt and nut to attach it to the metal part. I only need the diameter of the hole in the metal part, the distance from the top of the hole to the top of the metal part and the width of the metal part to make one for these printers :)

For the Ender 3/CR-20, it would be great to have the end have a threaded post and nut that would just replace the factory part that attaches to the upright metal part. Similar to this, but not so large and gaudy of a nut. https://www.thingiverse.com/thing:2988540

More like the end of this one. https://www.thingiverse.com/thing:3002160

Great work, I need one! ;-)

Edit: Perhaps the better thing to do and for easier printing, would be to take the tabs off the wall holder and put a threaded portion on the back of that along with a matching nut. The width of the inside back of the bracket is 39.69mm (there's a slight radius at the bent edges) and the center of the hole is 20mm from the top. Hole diameter is 30mm. This would allow use of the factory bracket on the Ender 3, CR-20, and CR-X.

Spool Holder for Ender / CR 10
Ender 3 Spool Holder upgrade

Alright, thanks for the information! I'ts difficult for me to make a CR-10/Ender 3 spool holder since there are very little reliable ones on Thingiverse, but with these measurements I think a spool holder should be up this evening (CEST timezone). I'm glad you like the model :)

Awesome! Let me know if you need any other info or a picture. I have a CR-20 and it has the same upright as the Ender 3 and CR-X. Will definitely print the holder to test for fit for you.

Make posted, thanks again for the additions!

Did you enter this design in the 3D Printing Nerd's contest? You should before someone else does.

Yes I did (https://www.myminifactory.com/object/3d-print-filler-the-filament-holder-that-fills-your-printer-71449). And even if someone steals my model, they're breaking the Creative Commons licence, so no worries :)!

a wall mount would be nice

Of course! I will try to get one up this evening!
EDIT: I just uploaded it, hope it works for you!

I would be interested to see this fit on 2020 extruded aluminum! Great design!

I am planning to make a brace for the CR-10 and Ender 3 (and any other printer using 2020 aluminium). Thanks for the kind words, I'm glad you like it!
EDIT: I just added the brace! I can't test it since I do not have any 20x20 objects, but I hope it fits :)!
