I use the RT systems software for programming my radios as it allows me to easily copy and paste between them. Each radio has a different programming cable and now with mine and those I've obtained for friends, I have quite a number. I made this hanger to help keep them organized and easy to find the one I need. Maybe you don't have the same cables but here's an idea on how to organize stuff like this.

The 2 pieces are printed with PETG, 15% infill and no supports.

Requires four M3x16 wood screws for assembly.

I design everything using OpenSCAD which is free to download and use. The source file is included here.
