Prusa MMU2 Spool Holder Tray Replacement
thingiverse
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 none 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.
