This is an addition so you can mount your BL Touch with the excellent Luckyman blower.
It sits nicely on the left side of the blower and utilises one of the existing screw holes for the blower. You will need an M3x14mm screw for the bottom hole and the existing bolt, which it shares with the carraige wheel, is fine.
I printed mine in PETG to match, but PLA will be fine. There is no risk of heat warp, unless you're in an enclosure printing ABS.
Printed at 0.2mm, 30% infill and oriented as shown in the picture, so you don't need any supports.
Offset for the sensor is X -41, Y -11
