BTT Offset Filament Sensor Mount

thingiverse

I printed the original by pjm237 https://www.thingiverse.com/thing:4749302 but found that the filament didn't line up for me and that the exit of the BTT sensor was too close to do much about this. I loaded the stl file into OpenSCAD and adapted the design to give an offset which seems to work for me. You can see in the pictures that it lines up well (might still be a bit close to the Z axis screw...) I also found that with the offset I could easily remove the sensor as the M5 Nyloc nut was now outside the BTT sensor housing. I bought a replacement longer (50mm) M5 hex screw but I am not sure I needed to - it gives me options if I want to mount something else here. I also messed about a bit with the lip at the end of the mounting block to make sure it was a snug fit on the wheel/axle bracket without having to fully enclose it (which I thought would make for messy printing with supports etc). It seems to fit snug and doesnt move when extruding.
