MMU 2 Filament Spool Holder

My solution to the Prusa MMU2 spool holders.

I found the stock Prusa roller trays overly complicated, prone to jamming, and space hogs.

Over my years of 3D printing, I never had good luck with roller trays. They tend to jam, the rolls fall off, and are sensitive to the filament rolls rim design.

I wanted a way to hang the spools and reduced the space needed. I also needed a better way to control the ejection coils.

I built my stand out of 1/2 PVC pipe. I am feeding the PTFE tubes
