My little Roland sits on a lightweight microphone stand. In order to minimize the number of items to take with me I made this hook that protrudes just outside the amplifier. You will need a M6 nut (preferable with a grip like https://www.printables.com/model/847181-hex-bolt-head-m6) and a rampa insert.

The printfile is for PLA. It has reinforcement at the overhang.
