This remote control has a bad UX issue. The toggle for the input source (labelled TV/AV) is very close to the main on/off button. When switching on, it is easy to accidentally also press this button while switching on.

This clip adds a collar around this button, so that you no longer have to take care.

A second version is included in the FreeCAD and 3mf files, that is thinner and made as a loop. May work better when printed with TPU.
