Prusa MK3 Spool Holder with Bearings

thingiverse

This is a spool holder designed specifically for Prusa MK3S printers or any other Prusa i3 model printer. The top of the main plate should be precisely 6.25mm x 40mm in size. It uses several 608zz bearings to significantly reduce friction between the spool and the holder, making it a crucial tool for printing very soft flexible filaments. In addition to 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 inches long The bearings fit snugly inside the spool cylinder. Alternatively, you can use 8mm hardware. No support is required for this object.
