3018 pro control panel

Since I am using bcnc to control my router I searched for an easy way to stop the router quickly if something goes wrong.
I realized that the controller board itself offers three contacts that are evaluated by grbl:

Reset/Abort (A0)
Feed Hold (A1)
Cycle Start/Stop(A2)

To use this contacts safely I designed a combined case and mount.
I also created a pcb for the push buttons (12x12mm). The gerber files for the copper bottom side, the board-profile and the drill file are also attached.
Since I milled the pcb this files are mirrored vertically.

To mount the case I used following things:
4 nuts M3
4 screws M3x16mm
1 screw M5x16mm
1 washer 5.3mm (DIN 125)
1 t-slot-nut M5 (for 2020 profiles)
Dupunt connectors and cable
