A passthrough filament sensor for the Prusa Mini+ which is mounted in place of the stock extruder in direct drive setups.
I recommend you print this part in PETG/ABS/ASA and not in PLA/PLA+.
You will need a few bits of additional hardware for this (on top of the Prusa Mini Filament Sensor hardware itself), most notably:
- 2 Passthrough style PC4‑M10 (M10x1 thread) PTFE couplers (PTFE tube must be pushed to the internal stop) (required)
- 2 M2 heat set inserts (optional, but make the install cleaner)
- 2 M2x10mm screws (optional, but make the install cleaner)
- Extra 4mm OD PTFE tube (I recommend 2.5mm ID)
- Zip ties for strain relief on the internal mechanism and strain relief for the extruder cable loom
Please see the photos for guidance on how to assemble (and don't forget the M2 screw which attaches the PCB to the board from the side).
