Switch box

Who knew this simple box could be so difficult.
I was keep on having problem with slicing, so I remodel this 4 times.
Finally I found the problem, and then building plate failed on me.
I plan to put a glass over the building plate.

This is a switch box, made for two small switches, and wires will be placed inside of the box and there are tiny openings for wires to go through. This will be another part of my printer upgrade.
