Recently, I bought a PSU extension cable kit from Formula Mod

There are some combs on each cable, but they are not enough to make the cables look good

Also, this cable has a shorter diameter than the default ones, so it needs custom combs that you can't buy in the shop

So, I've done my own cable combs

P.S. I left the .f3d file of my model so that you could create your own number of Pins

Printing:

Material: PLA or other
