I needed a printable quick disconnect for a project. So I designed one, 2 pin. pretty easy to print on a prusa I3 MK2 some support needed. kinda fiddly to install the male and female headers, I'm still working on that.
V2 turned out much nicer, if using an rj45 cable like I did take all the other wires out except the two you are using and push back the material, makes installing the female header much easier.
