MMU mini spool MK8.1

*** An updated version can be located here: https://www.thingiverse.com/thing:4353137 ***

Update: Added cartridge 2.2 (not tested yet) and secondary wheel holder 2.2 - both reducing tolerances and directing the filament to the wheels

Update: reduce gap between secondary wheel and its holder to eliminate filament getting off the wheel

This is a new re-design based on the Prusa MMU mini buffer MK8 by Steveps3 (https://www.thingiverse.com/thing:3970400)

This is a complete re-modeling but parts could be compatible with the original design

you would need to print 2 x arms and wheels
everything else to be printed once

I added M10 connectors supports and moved the intake to the center to avoid unnecessary friction

when using the secondary wheel (front one) - you only need to assemble one M10 connector. you have the option to install two more and use a PTFE tube between them instead of secondary wheel

Added a base without the off to the side connector holder (which is not needed anymore) and bottom with a lip to guide the filament into the wheel

Added secondary wheel to reduce friction

Also added a longer cover to eliminate filament tangling with spool
