I finally got a chance to print the MakerBot holder you updated for us at the library (I went ahead and made an account for the library) and it is AMAZING! It's the perfect height and the spools no longer bump into the frame. I printed your filament guide as well and they're working so well together! Thanks again!

Great news!
Thank you for testing the taller spool holder for Makerbot spools!

The new Spool Holder for Makerbot spools can be downloaded from the Thing Files or https://www.thingiverse.com/download:5121100

Hello, could you please upload the source file? I need a taller holder and/or the ClipOn part I love the fit and feel of it, and could really use it for another project.

Thanks for all the work! I'm running must of your designs.

Thank you.

How much taller and how wide do you need the new holder to be?
The standard holder is 100 mm wide and the newly uploaded narrow addition is 70 mm.

The holder that came with the printer is the same length as your spool holders but they're at a different angle.

The width is just fine, I printed the 70mm and it's great.

The filament holder looks really good on your printer, in Prusa orange! - There seems to be no need for a taller holder unless you also use filaments on larger spools.

The steeper angle of my filament holder is to give the frame less stress, but at the same time there must be room for the filament guide.

The Inventor source files are closed and will not be available. But I will be happy to improve the design and post the result.

The filament is not Prusa orange but of local source it's not as bright as the one from Prusa, and as for the source that's totally cool I'll give you a shout out if I use your STL.

And again thanks for the great parts!

New stronger Prusa i3 MK1, 2, 3 version (V2).

Has new internal structure to make the holder more stiff and rigid, an improved holder angle and allows for printing in full height.

Hi, can you send me the file on .step or .xt format? I would like to make some modifications. I´ll give you the credits, of course. Thks!

I can change the clip size, if you need the holder for another printer. The top part of the spool holder is pretty simple to model.

will spools with the smaller 32mm hole work with this holder? There's no dimensions in the description of what size spools will fit.


If the spool center hole is larger than 26mm (1") it will go on and can be used on the holder.
Yes your smaller spools should work on the holder.

The model was just made public 5 days ago and is missing the ClipOn for easy and secure locking to the frame.
But it is interesting, that we ended up with a similar design...

Thank you for this!! This holds a typical 1KG spool weight just fine?

The photo shows the holder with a 1kg PET filament spool.
I have been using it with 1kg spools without problems so far. Just measured the arm bend down, it is approx. 3mm when loading a 1kg spool, but PEG is also a little springy.
Print with 3 or more perimeters to make the holder strong - the infill percentage is not as important (5% or more).

Thanks! I just printed one. I Forgot to change the perimeters to 3 :( but the top and bottom were 3. I did 10% infill and it seems to be holding up. I printed with Monoprices PLA + so its supposed to be as strong as ABS
