Model origin

The author remixed this model.

Differences of the remix compared to the original

had massive problems with the filament sensor after installing MMU2S.

I realised it was because of two issues: first, there was too much tolerance on the original prusa parts, and second, there was not enough lavrege on the idler to trigger the sensor correctly.

I extended the MMU chimney by 10mm and the idler part that triggers the sensor by 10mm as well.

The little extension on the end of the idler that is the trigering sensor in my design is part that you adjust according to your needs by sending it down. In my case, 2 mm was perfect.

I printed both parts in ASA CF 0.2mm with 100% infill. You can use PETG, ABS, or ASA.

I add STEP files so you can easy edit it in Fusion 360
