MMU mini spool MK8 with M10 connectors and central intake

Update:
a much improved overall design is at: https://www.thingiverse.com/thing:4353137

This is a new cartridge for the mini spool mk8.
I added M10 connectors supports and moved the intake to the center to avoid unnecessary friction
Added a base without the off to the side connector holder (which is not needed anymore)

Also added a longer cover to eliminate filament tangling with spool, added a second lid (no pattern) to be printed without top and bottom layers and hex infill @ 10% - gives a nice hex structure (and prints fast)
