Simple minimal thickness cover to protect the rotary encoders and buttons on a QMX when in a pack. The four 10mm magnets can be 1.6mm-2mm thick. The knobs are slightly modified versions of the KF0ARE QMX knobs here on Printables. I added a hole on the side for a M3x4mm set screw for a more secure fit. This setup along with thinner rubber feet on the bottom reduced the overall thickness of the radio by a little over 10mm.
