I do a fair amount of repeating work and use a corner jig to speed work piece setup along. File is set up for 1/2" thick, and I’d recommend a 12" x 12" piece of material. Holes match up with hybrid table and the uses the t-nuts and screws that shipped with the machine. You’ll want a 1/8" cutter for this, 1/4" is just to big for the screw holes.
This might work. Added a pocket to fit the green work piece clamps. Untested so check the file before hitting the go button. If anyone does decide to make this, let me know how it works.
