LEGO compatible 2x2 grid solid

I found a modular display that I really liked and wanted to add some studs to the base in order to secure my LEGO models. The other LEGO models I found were slightly too small, so I created this one. It is a solid, and the plate is not LEGO plate depth. The diameter of the studs is 4.9mm instead of LEGO standard 4.8. This created a nice, snug fit.
