Another Parametric box with holes

It's another simple parametric box for small electronics things, with nothing more fancy than a lid and a rectangular hole on each side.

Set the hole height to 0 for no hole in that side. The hole goes up to the top of the box, and a 'lug' is printed on the lid to fill the hole from the other side, so that you can just drop in any item that would stick out. This makes it a little delicate so the walls need to be quite thick.

I used this to house a USB pwm controller (pictured and .stl included).
