Emergency Button Box

Needed an emergency stop for my laser projectors. The design uses speaker wire and has a strain relief for the cable. Tabs vs no tabs is for buttons that easily rotate and need some locking. The interlocking parts are made with 0.2 to 0.3mm clearances.

Hardware used:
Panel Mount Button/device of your choice
4x 25mm dome M3 screws (cover)
2x 10mm dome M3 screws (cable clip)
14 AWG Speaker Wire
