Tray I designed to hold my self-centering vix drill bits and the adjustment allen wrench. Unfortunately the exact set is no longer available on Amazon, but the sizes are pretty standard.
The end of each slot is sloped down so you can push the end of the bits to easily remove them from the tray.
I would like to eventually redesign the base to fit the gridfinity standard.
