This is a mount to attach the BTT Smart Filament Sensor to the BIQU B1. The mount is designed for use in combination with the BMG extruder and closely aligns the filament path.

Print as orientated in the picture. No supports are needed. 25-30% gyroid infill. If possible print the arm in PETG and the case in PLA for a nicer finish. Hole tolerance is 0.3mm

To install you will need 4x M3 10mm screws. The arm has built-in plastic threads. Try to avoid repeated assembly and disassembly. I don't recommend installing PTFE tube on the exit of the sensor but a small one inch piece on the entry to the BMG is fine.

The cover plate is adapted from the case provided in the BTT github page,
