Minor mods for MMU2 wall mount

thingiverse

I made a few minor tweaks that proved to be beneficial...\r\n\r\nI adjusted the filament guide slightly to accommodate a Festo thread. Mounting it from the back of the spindle instead of the front creates a smoother downward path and helps with filament unloading, thanks to the PTFE.\r\n\r\nThe Festo thread used here is based on Thing 3272446, which you can access at https://www.thingiverse.com/thing:3272446 . It employs the same type of Festos mentioned in that design.\r\n\r\nI also added standoffs to terminate the MMU2 PTFE tubes directly beneath the guides.
