I needed an electronics box to house my rather long 3-fase 4-way switch to switch my heavy equipment behind a rpm controller.
This box is 190mm wide, 110mm high, and 150mm deep. (can fit equipment less then ~140mm long).
The hole are easy to drill to size with a step drill bit. I made made center points so you can easy drill in the center.
I also added 2 screw holes in the horizontal direction to fit a DIN rail.
