I am working on a series of 2 unit x 3 unit Gridfinity tool trays, to fit into my Dewalt T-Stak series tool box, as well as elsewhere. I have added a 12mm magnet hole to the center of every square for an optional countersunk screw magnet.

This one is a rack for all of the usual drafting and sketching tools I use. There is an optional pencil cup for pencils to rest on the ferrule or wood, instead of the lead. You will need the following: 1x 2x3 Pen Rack Floor 2x 2x3 Drafting Rack plates 4x 29mm spacers 4x 10mm spacers 4x M3x50 bolts Optional Pencil Cups as needed.
