Radius Gauge Gridfinity Stackable Storage Box

I've been trying to sort out my 3d printer gear with Gridfinity items and I had previously downloaded and printed these gauges. The box was so close to Gridfinity size I thought I might as well make one up. I made the gauges a fairly loose fit because I wanted to be able to pop them in and out easily. That's also why I have the cut outs along each side. This can be printed with no supports.
