Prusa MK3 Spool Holder with Bearings
This is a spool holder designed for the Prusa MK3S or any Prusa i3 printers. The dimensions of the top of the main plate shoud be 6.25mm x 40mm. It uses some 608zz bearings to reduce the friction between the spool and the holder. It makes printing very soft flexible filament easier.
Besides the printed parts, you will need:
- 2 x 608ZZ bearings
- 4 x 5/16″ nuts
- 1 x 5/16″ washer
- 1 x 5/16″ threaded rod, at least 4″1/4 long
The bearings go inside the spool cylinder. 8mm hardware can also be used.
Support is not needed.
