I use an AMPS style (ball) mount in my vehicle and needed a clean way to mount the ICOM IC-2730 faceplate to it. This is a simple but sturdy design and only requires 2x M2.6x5 screws to attach.

I recommend printing on its side with supports to allow distribution of stress around the model rather than printing on its back.

Printed on a X1C with PAHT-CF using 3 wall loops and 40% gyroid infill.
