This is the modified version of the MMU3 selector finda with chamfered filament intake that makes it easy for the filament to slide in. Sometimes, espesially when the filament tip is very flat it hits to the side of the hole on the selector, I modified the filament hole to be chamfered to make it easy for the filament to slide in.
I also included my modified version for T8 nuts which is suitable for brass T8 lead screw nuts that has 16 mm distance between screw centers (Prusa's has 19mm afaik). This was required because I didn't get the stepper motors from Prusa.
Update 20/08/2025: Added R4 models (T8 and Prusa) with the chamfered filament intake.
