Hi all. Just wanted to chime in. The very first J1772 3D printed inlet was designed by me. It has been on the thingiverse since Feb 24 2013. I know I was the first because I searched everywhere, couldn't find one, so I made one and uploaded it.

It is open source and free to use non-commercially. It is interesting to see how many variations have spun off this project. I am glad to see I have made an impact.
Anyways, I have been selling 3D printed units for nearly a year, and couldn't keep up with demand. 3D printed units may also break relatively easily.
I selected the most popular version, and got it setup for injection molding. Please check out the post in the business section.
