This is a simple cable wrap that can be hung onto something. I use them to hang audio cables (~6m) off an IKEA VARHAUG room divider. 

I print them flat on the bed and you can print 3 at a time as they are on an MK3S+. I've printed mine in PLA at 0.3mm and they do the job fine.

You can use the OpenSCAD file to change the dimensions of the model, if you need it to be longer, wider or thicker (at the moment it's pretty thin but it works).
