CHAdeMO plug construction - hwthomas/ccs-chademo GitHub Wiki

The following taken from https://www.thingiverse.com/thing:121581

" The plug tip and pin holder MUST be printed in a high temperature plastic such as ABS. Do not use PLA for the tip and holder. The rest of the parts can be PLA if you prefer. My layer thickness was 0.3mm for the orange ABS sections, and 0.4mm (different nozzle) for the white PLA parts.

I have deleted older revisions to make things clear. This one is my final version, so I will be making no further updates.

After the plug is printed, the holes for the pins should be cleaned/drilled with 23/64" for the 9mm holes (pins will slide in nicely, and will not wobble). The holes for the data pins will need to be drilled for whatever thickness of neck you have for your data pins. I used 2.8mm EDM brass rod. So I drilled out the holes with a 7/64" bit and then once more about half way down with a 1/8".

The tips of the data pins are: digikey part number ED90409-ND (gold pins) are soldered onto the center of the rod using a jig.

9mm power pins are here: https://1drv.ms/u/s!Ah-wSazeIk6il1o7ojQ8hqimbJr_?e=BBUD0P

entire assembly is here https://1drv.ms/u/s!Ah-wSazeIk6il1yQpJV3vVhzOeBR?e=4ZLSuz

The power pins are 9.0mm nominal with a tolerance of +0.0 -0.1mm
