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.

This object was designed using Fusion 360
