Now for the fun part of this box. I found some good information on Kenney's blog and instagram. He gave enough information for me to figure this jig out. The 4 sides of the box sit inside of the jig. The circle template sits on top of the pieces and is secured with screws. The one key for this to work is to make sure the circles on the far right and left match exactly because they are actually the same circle on the same corner of the box.
