PiKVM v3 metal case under-shelf mount

The PiKVM v3 hat with metal case is really cool, but I needed a way to keep it off my workbench.

This bracket allows the PiKVM to slip in and still have all the ports accessible.  Plugging in one cable on the left and right inevitably causes it to stay securely on the mount.
