Limit Switch Mounts for 3018 CNC Router/Engraver

Limit switch/homing switch mounts for the inexpensive 3018 CNC router/engraver. Might fit other similar machines like the 2418, 1610, etc. if they use 2020 extrusions for the frame. Once they're wired and enabled, limit switches allow you to home the machine and set work coordinates like on the larger machines.
