Wall cable junction box cover

I want to make my lighting smart, and the switches should still work, but there wasn't enough space in the cable outlets to accommodate the additional smart actuators. 

I was inspired by two models from printables and i created a cover with more space. Its divided into parts to print it without support. Upper and lower Part must be glued together.

The cap can by unmonted to have a better access to cables and electronics inside.
