3.5mm wire clip/organizer
thingiverse
These are some wire clip organizer things that are modeled after a set I saw online. I'm not sure they fit all sizes of wires, but the cord I used for testing was a USB-C cable that was about 3.5mm in diameter. I wasn't able to get a physical retention clip working as FDM printing can't quite go that detailed, but this seemed to work pretty well.
