Hey all,

Working on a quick change system for my 3d printer, kinda stuck on how to do the electrical connections. If someone could tell me what the black & gold connectors in the picture are called? Or if anything has a better suggestion, I'm all ears. I dont have a final count on the number of connections yet, but its prob in the 20-30 range.

Thanks all

thank you! I didn't even know what you search for.

The #15 looks like a good option, but there's also load of other connectors on ali for me to sift through.

still open to suggestions if anyone else has any.
