NOTE: UPDATED Version WITHOUT Brake for new MMU2s can be found here (Complete redesign)-> https://www.thingiverse.com/thing:3571725
A multi-spool holder that works with Wall Control pegboards. I wanted a spool holder that got the spools off of my workbench while still keeping the Prusa brake system for the MMU 2.0. You can print the arms with or without the brakes (the brake arm requires some minimal supports) depending if you need the brake system for your setup. The bearing plugs are to optionally cap the end pieces for a bit cleaner look. Uses the 608RS bearings that came with the MMU2 holders.
Requires you to print a minimum of 2 arms (with or without brake) and 2 spool wheels. Printing 1 additional arm and 2 additional wheels will allow you to add a second spool.
Peg-board can be found on Amazon
The holder levers are the original Prusa parts, and the same 2x M3x12 screws used for each brake. (https://www.prusa3d.com/prusa-i3-printable-parts/).
Thanks to the following two spool holders for the inspiration behind much of the design here:
