This is a tray I doodled for holding all of the usual tools for working on my 2020 based Hobby CNC systems, Laser etcher, 3D printer, etc. It's based on a 2x4 Gridfinity foot print. I added 10mm magnet holes for variety ( I had a bunch). Socket holes on the left fit most 1/4" square drive sockets and Hex bits. Parts tray in the center. Then L wrenches and hex driver holes on the right, as well as a spot for a mini adjustable wrench, and pair of nippers. All holes are intended to fit the tools loosely. I don't like having to wrestle the tray for a tool while I'm holding something in place.
