Anet Extruder Filament Guide

Hi. I printed the part, and it works perfect even if I did not enlarge the hole for the filament. I tried different filaments coming freely though it, and this was enough.

But what do you mean with

"However I would recommend that the hot end throat be placed even with the mounting plate so that the heater block is furthest possible distance from the extruder carriage."

I always thought, that the throat should end as close as possible near the gear, so that the gap is not too big. So I had to choose the version with the guide 1,5mm. Would it be better to enlarge this "gap" between the gear and the heat break? And why?

What a great design, it works perfectly. (however I did have to file the hole for the screw, as both holes did not align)

Thank you so much, now I can Print PTU on 60mm/s.
Nice and easy Design!

Hi!

Thank you so much for this simple, but very effective design! before I could rarely print flexible filaments at 5mm/s speed, but now, I can even print them at 15-20mm/s without any problem.

You're welcome.

can you link the blue printed part(s) from the first picture? :)

Hey Leo!
Is this thing designed for a stock Anet A6 printer (I think the A6 and A8 are the same when it comes down to the extruder right?)? Or have you modded your printer slightly? It seems like in the first picture that your extruder gear is a lot closer to the metal block the 3D-printed part sits on than with my printer...

Hope to hear from you!

I don't have an A6. No guaranties but I would guess the extruders are the same.

That part of my printer is stock.

Ok thank you! I’ll print it then

Ty, TPU prints fine now with this upgrade!

Glad to read.

Flexible TPU just works now! Thanks.

We are happy :-)

Works very well. Thank you!! Now i can print TPU without any worries.

Sounds great.

Hi Leo,

Thank you for your work.

Another daft question, me too...can I put it on a Anet A3 3D printer ?

Thanks for your answer.

Of course you can print it on an A3 3D printer, any 3D printer for that matter if they can handle PETG or ABS filament.

Thanks for your answer.

I realised that I asked in the wrong way : after printing the filament guid, does it will fit in a Anet A3 extruder or it just fits on a Anet A8 ?
The extruder block is the same for both printers ?

That I can't answer as I have no knowledge of the A3.

Hallo Leo,

funktioniert tadellos, Danke.

Freut mich.

Hi Leo.
Daft question, but would these print better flat on the bed?

Cheers.

Legit question. I recommend printing upright because the surface will be nice and smooth where it counts.
However are free to print flat. I think that should work as well.

Thanks Leo.
Makes total sense.
Upright it is :)
Thanks as always.

Brian

I made this for my Anet A8, it works great and fits perfectly. Great work, Thanks!

You are welcome.

Some throats have sharp edges and tend to shave the filament. I just opened up the extruder after a long session on printing ABS and found a tiny red ABS rats nest all wound up in there. It was not long from fouling the roller and failing the print. So this is a help with any material. This might be a good reason to spend the money to buy some nylon. Anything that needs to be slick and heat resistant can benefit from nylon. PETG is a good 2nd choice.

PS... You can take the burr off the throat, but many dont have the tools to do that. Its just easier to use this and be ready for flex as a benefit.

OK the fan and heatsink I guess?
What is the difference in the four guides you've published.
0.2 0.5 1.0 1.5 ?

the differences are the height of the throat above the mount. As the author stated in the description.

Thnx for the explanation, have to brush up my English.

Leo, what is the blue part in the big picture for?

regards Piet.

It's a fan holder so you can remove the fan.

Anet A8 Fan & Sensor Holder
by Leo_N

Works perfectly for flexible filament. Essential if you want to use flxible filament.
I printed mine in PLA. It turns out that PLA on PLA filament tend to jam. Do not expect to use it for PLA if printed tin that material.

can this be printed in TPU?

Hi. Relative newbie here, currently printing your rear brace design to match the front one I've installed.
Is there any reason why I cannot use this guides for any filament? I'm finding it difficult to load even PLA and this seems like a possible solution.

Did you enlarge the hole with 2mm or 2.2mm drill?

Not at the moment; I haven't printed it yet. I was asking before I tried it in case I messed something up :)
If drilling the hole means it would work I'm sure I can manage that as long as I don't melt the PLA doing so.

OK, I misread the post. This guide is intended for flexible filaments. However it doesn't hurt to use it for PLA as it will helps makes insertion it a bit easier, IMHO.

Would I still need to enlarge the hole? Like I said, I'm a newbie - and thank you for all your replies to my probably obvious questions

Yes because the hole should have a super smooth inside finish so the filament can slide easily. Don't worry about the drilling part. Just take your time and do it slow.

Thank you :)

Hi, could you provide the cooler support link that appears on the image?
Thank you

What is the different numberings for the files?

Using a specific file depends on how much the Teflon nozzle throat is protruding over the holder block.

Is there a reason for printing this on it's side?

Not really. I did it mainly because of a cleaner surface.

just want to say thanks! I've been struggling printing TPU. Once I printed and installed this it now prints like a charm! You're a life saver!

You are welcome.

Somehow my Ninjaflex still managed to escape the extruder.

Honestly I didn't think that was possible.

You sure that the extruder temp was high enough and the feed was done with a hot extruder state. Feed speed too fast maybe?

Could you possibly share a link to that nifty fan attachment??? Thanks

I like yours designs and this works perfectly in my Anet A8, thanks Leo

Glad to read :-)

could you make a version for a bowden conversion without any indentation for the heatbreak?

OK, that I don't understand :-/

Gemessen am Profil kann ich es vermutlich auch einfach auf Deutsch beschreiben:

Die Filamentführung hat in den unterschiedlichen Versionen eine Vertiefung wo vermutlich ein Stück der Heatbrake reinragen soll.

Bei einer Bowden Modifizierung schraubt man so ein Tube-Push-Fitting dort ein wo sonst dieses Gewinde drin ist, dieses ragt auf der anderen Seite nicht über, daher war die Frage nach einer Version mit 0.0 mm 'Einbuchtung'.

Aber ich bin auch gerade am überlegen das Bowden plus flexible Filamente sowieso nicht wirklich harmoniert, daher ist das vermutlich ohnehin eine Schnapsidee.

Ich dachte das dies halt auch das einfädeln von regulären Filament vereinfachen würde, das ist manchmal schon etwas frickellig bis es wirklichen in die Heatbreak oder eben das boden-tube-push-fitting-ding reingeht.

Ansonsten habe ich viele deiner Upgrades an meinem A8. :)

Now I understand :-)

Du, da würde ich einfach die 0.2mm Version nehmen den die habe ich entworfen für den Fall das am Loch ein Grat vorliegt.
0.2mm hat für flex und das Einfädeln keine Auswirkungen.

Ich habe keine Erfahrung mit flex. Filamente und Bowden aber was ich so lese ist das keine optimale Kombination.

Perfect timing! I just got in my TPU order in last night! Printing and thanks again!
