Love the original design, but filament sensor wasn't perfectly aligned with my BMG extruder, so I remix it a little bit, here are the changes :
- More accurate, the part can't move anymore when in place
- Remove the need for a M4 nut, directly screw the M4 screw in the printed part
- Align filament sensor and extruder
A 52 mm TPFE tube fit perfect beetween extruder and filament sensor, no gap
Enjoy, and thanks again for the original thing !
