Bracket for attaching the BigTreeTech Smart Filament Sensor to a vertically mounted extrusion motor, such as what's found on the Ender 3 line of printers.
This works best when the extruder has a flat surface to mount against - in my case I'm using a spare Bondtech BMG that I've put on my Extruder motor.
Designed to accommodate a short length (<80mm) of 1.75mm PTFE tubing to guide the filament round the corner. I've not tried it without this.
The model has clearance for the Ender 3 V2's lead screw - no promises about any other bed slinger priners!
The mount adds a few mm to the required screw length - in the case of the BMG, I went from 35mm screws up to 40mm screws.
Prints with no supports required - the STL should already be angled at the 45° required for this.
As a side note, if you're attempting to use this with the SKR Pico and are using a BLTouch (or have the Z-Endstop free for some other reason), you can use the E0 Endstop and the Z Endstop connectors & configure 'gpio16' and 'gpio25' as your runout input pins.
