MMU2 Idler body with gear (extruder)

MMU2Idler with gear based on prusa idler body version M1
My version of my mod is: G1.V1
Inspired by https://www.thingiverse.com/thing:3282939

First time I tried to get MMU2 working the idler body cracked and the result was almost no pull on the filament.
So I redesign the idler from using two screws to instead using one gear(with tightening screw) and one screw.
I design it to use an extruder gear (I used a spare I had)


I printed this at 0.1 mm layer silver PETG 20%Infill no support
