Wall Mount Spool Rewinder Adapter
Description
Just got your new MMU2/S, but unable to enjoy it because of the clutter? This is an adapter that allows the [Universal Auto-Rewind Spool Holder](https://www.thingiverse.com/thing:3338467) to be used with the [Prusa MMU2 Wall Mount Spool Holder](https://www.thingiverse.com/thing:3157502). Description --------------------- After purchasing my MMU2S, I did not have room for 5 spools, Prusas filament buffer, and the printer all on my surface. I built a wall mounted setup with the Wall Mount Spool Holder linked above, and removed the Prusa filament buffer, just going straight from the spools and through one PTFE tube to the back of the MMU2S (6th picture). This worked well and looked amazing, but I had issues with filament tangling when the MMU backed up the filament for a change (7th picture). I needed an auto-rewinder, but couldn't find anything compatible with the rack I had already printed. I had already used a lot of filament to print the rack, and already had the holes in my wall, so I really did not want to use something else entirely. This led to me creating this adapter.
