I created a square version without and with security bridges on top for my Flight Simulator Panels.

The bridges should avoid accidentally touches.

Now the plate will be mounted from above, instead of from the "hidden side".

Additional for the secured version i made the knob 5mm shorter, to be concise with the top of the frame which will be mounted on a 4mm thick plywood.

If your mounting plate is thinner / thicker, just resize the button.
