MPCNC Limit Switch Holder

Mounts on the 1" EMT tubing and uses a ZMA03A150L04 microswitch available from DigiKey for $0.79 ea.
Made in two parts to allow placement after MPCNC assembly. Joined with 4-40 screws.
Soldered #22 two-wire cable also from Digikey.

This is about as small a limit switch design as I could think of.
