Update 17.1.2022: Added two new smaller sizes and renamed the files for clarity.

This is a compact filament spool holder. If you use more than one spool at a time, you can stagger the position of the holders to fit them in a smaller space. The parts snap in place, so you don't need to worry about them falling off. Fully printable except for the 608 ball bearings.

There are four sizes of the spool holder with varying widths. Choose the smallest one that fits all your filament spools to save desk space. For example, the "70mm-spools" can be used with spools up to 70mm wide. "90mm-spools" is compatible with the metal shafts from MMU1 spool holders, and "100mm-spools" is compatible with the metal shafts from MMU2 spool holders.

Print instructions

I recommend using a thick layer height for the parts for a faster print time. I have only printed them in PLA, but other materials should also work.

Shafts have to be printed in an upright orientation, so you must add a brim and supports for them. I recommend using around five perimeters to make the shafts strong enough.

Let me know if you have problems with the spool holders!
