A 4x1x6 Storage Block to hold my Makers Cabinet tool set. I'm sure the venn diagram of people who have this tool set and also use gridfinity is pretty small, but if you're out there, here ya go. The thumb screw slot is basically press fit, as I rarely use it, I didn't want it falling out. If you press it in, you'll need a set of pliers and something soft to protect the brass to get it out.
