Giá đỡ công tắc giới hạn cho mô hình Elegoo Phecda

simple limit switch system for Elegoo Phecda laser using basic momentary switches - ie the type from an Arduino kit.

Needs a bracket or something attaching to the Gantry to trigger the Y Switches

For the X switches on the gantry I glued them into place using CA glue, cut outs on RHS due to the stepper motor mounts.

Y switches I marked the slots and drilled holes for screws 

I used switches similar to these
