Summary

Simple AIO Cable Comb (designed for 13 mm).
You can resize it in the slicer using XY scaling to get these sizes:

11 mm → 0.8462
12 mm → 0.9231
13 mm → 1.0000
14 mm → 1.0769
15 mm → 1.1538
16 mm → 1.2308

I recommend using very low infill so it's flexible and doesn’t put too much pressure on the cables.
