I designed this bracket to mount the BigTreeTech Smart Filament Sensor to a BMG or clone extruder. Mine is mounted in a direct drive configuration but I'd imagine it will also work on a bowden setup.
You'll need 2x M3x40mm socket head bolts and a short length of PTFE tube to attach the bracket to the extruder and the original 6 bolts from the SFS are re-used to attach it to the bracket.
Print settings shouldn't matter much, I used eSUN PLA+ at 0.2mm layer height, however given the stresses involved it would probably be better to use PETG.

EDIT 02/2023 I've been using this bracket in PLA for hundreds of hours now and it's been perfect.
I've also included the .step and .f3d files in case anyone should want to make changes to it.
