! Made for wires with an external diameter of 2mm. Can be scaled up in slicer. (200%=> 4mm)

Quite simple. Put is wires, twist it and get a nice cable.

One wire must be in the centre, then the others in the outside holes. 

After the wires are in and clamped in a vise, twist clockwise and the wires will twist together and, if the coating is not sticky, should advance by itself.

In the end, do a couple of passes with a heat gun to induce memory in the resulted cable, secure the ends to prevent fraying and done!

I recommend to print this in PETG due to its lower friction, but PLA will also work. No supports required.
