Prusa MMU Spool Holder

PVC and printed spool holder for MMU use.

"Scaffolding" is made of 3/4" PVC with elbows and Ts. As shown in picture, the frame has 2 parallel bars, 1 of which is behind the other, and the 3d printed parts thread onto the rod. The design allows for pivoting to allow replacement of spools arbitrarily without the headaches a common mounting rod would cause.

Each arm is numbered. There is also a threaded spot for a PTFE fitting, the type which allows full tube pass through. This allows easier access and less confusion when loading the filament as to which "slot" it's in and which extruder it's connected to.

This as one piece is too large to print on an I3 without being broken into pieces. I did not part it out as I have access to some printers which can accommodate it as a single part.

I printed with the number face down, to minimize filament swaps. I was successful adding a small amount of support at the end of the 2 round rods, your printer may vary.
