Switch housing for 22mm handlebar

Should fit your cheap automotive switch found in auto parts store. I used BL brand switch from Puuilo

Internal dimensions for space for the switch:

18mm x 31mm, height 32mm

Switch hole diameter 12mm

You need to drill your own hole to the cover part. I drilled and attached rubber passthrough for the cable I had.

Uses m4 hardware

I didn't use supports and printed so that the top surface of switch box is facing the build plate.

Printed with ASA. ABS/PET-G/PA-CF should be ok aswell

Has worked for me so far. You can use the switch even if going through some rough terrain. I use it for auxiliary lights in Tenere 700.
