Compact Filament Spool Holder

prusaprinters

<p><strong>Update 17.1.2022: Added two new smaller sizes and renamed the files for clarity.</strong></p><p>&nbsp;</p><p>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.</p><p>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.</p><p>&nbsp;</p><h3>Print instructions</h3><p>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.</p><p>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.</p><p>&nbsp;</p><p>Let me know if you have problems with the spool holders!</p>
