Hello , now I'm making female type 2 3d print as I mentioned in my e BMW project. So this is new thread for particular project. I made few printing and optimisations in order to get proper connection. Some modifications were also done on my 3d printer.

What filament are you using ? One of my concerns regarding 3d printing power connectors is temperature rating / flammability of the materials. By definition, plastics suitable for 3d printing have fairly low temperature ratings. Otherwise great job, hopefully you're posting your sketches to thingiverse.com ;)

This is my own work. Printing surface is cca 370X370x390 , but I'm not heating all 4 plates , only 2 for now. I didn't have need for that and need to put stronger power supply.

Very nice!

Where'd you get the pins,

what do you think the max current handling can be,

and at what temperature rise on the pins?

As a suggestion, even though it's more money, you might think about using fire retardant ABS filament if this isn't already.

Tnx,
I'm making pins from steal and brass on the machine. I think resistance should be the same as original . They are fitting whell , Material is material... 6mm metal pin should handle a lot of power. I didn't try more then 3 kw, i don't have so strong charger yet. And dobody complained at all.

I can attest that your connector is of good quality. I use the short version to charge from fast AC stations where you have female cable on station.
Pins could need a bit more polish, but they fit well, specially the small ones.
I can also tell you that pins from 4 pin AC male DIN (red) plug fit mennekes almost perfectly.
