Kobalt 3/8 Imperial Socket Set - Gridinity

I designed this 3/8 Imperial socket holder for my Kobalt socket set (both shallow and deep).  The holes are made to fit with about 1mm extra space.  I wanted to build this on a 4x2 so I had more options in my tool drawer. I used the gridfinity box template that has improved magnet holes and I didn't need to use supports, YMMV.
