Prusa MMU2 Spool Holder Tray Replacement

by rambopierce

I'm a Prusa fan, but I dislike the cheap blow molded trays included with the MMU2. This spool holder reuses the hardware included with the MMU2 ( bearings, rods, and yellow stopper flags). There are many spool holders out there, but I didn't see any that were designed specifically to reuse the hardware included with the Prusa MMU2. In addition to the print you will need a short piece of 2mm x 4mm PTFE; I used 100mm length and this adapter to hold it in place: BIQU PC4-M10 Male Straight Pneumatic PTFE Tube Push E3D-V6 Fitting Connector for Bowden Extruder 3D. The hole in the print is threaded to receive the BIQU PC4-M10. Be sure to taper the inside ends of your PTFE tube; my favorite tool for that is a HobbyPark RC body hole maker 0-14mm.
