Wonder if anyone can help on this one I want to mount homing switches

Wonder if anyone can help on this one I want to mount homing switches on my @ooznest cnc, I managed to get the x & y mounted without issue however I can’t work out how mount the z axis switch to so I can have it set to it’s highest point, can anyone show me how you mounted yours as the only guides I’ve found use holes mine does not have?

Cheers

Mounting is easy using the rail. I just made 4 (different mounts) of these for a conversion on my laser. This is not my design. Got them from Thingiverse.

Pros: Easy to Mount and Sturdy.
Cons: Potentially reduces travel

You could always make a bent wire setup (or whatever you find fashionable) that is mounted on the Z and at the highest position hits a limit switch that’s mounted lower on the Z carriage. I don’t have this setup on mine yet so no photos available unfortunately.
