A filament spool holder for the MakerBot Replicator 3D printers. It is designed to fit most spools and be 3D printed without support material.
It is made of two symmetrical halves which are held together with filament pins and two small cable ties. One can alternatively also use small 3 mm screws and nuts. (no glue required!)
The original CAD and netfabb files are supplied for easy design changes.
A longer version of this file is alos supplied so that extra wide spools can be loaded. Download the file "Split_filament_spool_holder_for_Replicator_3D_printer_v02 (135 mm spool width).stl"

  • Download the STL file (it contains both halves)
  • 3D print it it with MakerWare in standard medium quality
  • Remove the print from the build plate (a strait palette knife does the trick)
  • Cut two short 20 mm pieces of standard 1,75 filament. Place them in the two small holes
  • Press and hold the two halves together
  • Use two small cable ties and place them in the two holes which hold the halves together
  • Put the assembled holder in your Replicator 3D printer and keep the spool turning! :)

Invaluable thank you!

Thank you for your kind words :) We are glad you liked our spool holder.

I am printing this and it is walking on the replicator 2. anythoughts???? please help new guy.... picture attached..Thank you!

This spool holder works well on the MakerBot Replicator 1, 2, 2X and many other similar 3D printers. We designed it to be easy to 3D-print and fit many different machines.

I love it!!! Thank You very much for sharing this :)

You are welcome Mewalela! :) We are glad you liked it.

I've made several spool holders for filament other than makerbot filament and this model is the best so far. Even though you need to use zip ties to get it to work, its still the strongest and thinnest version ive made.


We are really glad you liked our filament spool holder. It is a bit of a banana-split-design to avoid support material.

just cranked one out, what a clever way to avoid support material as well as it being a very good universal spool holder. Gonna crank out a few more! Well Done!

Thanks for your kind words. :) Glad you liked the spool holder.

Very nice and useful thing :) thank you very much !!!

You're most welcome! Glad you found our filament holder useful.

This works GREAT on my Replicator 2X with the new 1Kg spools I ordered from eBay. Very simple and works perfectly. I even printed it out in low resolution for a quicker print and it works great. See my pictures from the MADE section. Now I need to print another one for my other side spool.

Prints without any problems and works really well with cheap Chinese filament spools (wider than MB).

A longer version of this file is alos supplied so that extra wide spools can be loaded. Download the file "Split_filament_spool_holder_for_Replicator_3D_printer_v02 (135 mm spool width).stl"

Nice work. Prints fine and does the job!

Great idea, but I would argue that there is to much surface contact between the spool holder and the spool it self. That leads to more friction. I would maybe make raised groves to minimize friction on the spools with flat inner hole.

Thanks for your comment. Your suggestions certainly would improve the design. We'll do that in a next iteration of the CAD file.
