Desktop ATX case foot adapter for wire shelf

This is an adapter to fit a desktop computer ATX tower case to make it more stable sitting on a wire shelf without the round case feet falling between the shelf-wires. It also allows the computer to slide smoothly forward/backward to access the back easier for connecting/disconnecting cables.

NOTE - the slots for the wires are not perfectly symmetrical with the round case-feet, you can adjust the alignment of the wires vs the feet by rotating them 180 degrees until the notches are aligned co
