Simple Prusa Spool Holder

thingiverse

This simple filament spool holder is derived from Josef Průša's core Prusa Mendel GitHub repository (https://github.com/prusajr/PrusaMendel). It's designed to hold Ultimachine-style spools. To assemble it, you need four printed bearing guides, four printed bar clamps, two 130mm m8 threaded rods, twelve m8 nuts, and sixteen m8 washers, along with four 608zz bearings. First, snap the bar clamps onto the top bars of your Prusa. Then, assemble the parts in the correct order onto the rods: nut, washer, bearing w/ guides, washer, nut, washer, bar clamp, washer, nut (30mm gap), nut, washer, bar clamp, washer, nut, washer, bearing w/ guides, washer, nut.
