A quick tool holder that attaches to the 5mm plywood to hold a caliper, tweezers, and 3 hex wrenches.

UPDATE:
After my tool holder broke I updated the design to be stronger. The new part is "tool holder V2.stl"

Print the "tool holder.stl" file, tap a M3 hole in the back hole and thread a M3x10 screw into it.

To mount the holder slide the plywood through the groove and tighten the screw (which can't be seen in the pictures).

I have also included the NX6 .prt file for those who wish to use it.
