Hi, In my spare time I have designed a replacement for the joystick coupler.
It it of my own design, different from the original or the one on Thingiverse, which is based on the original.
I'm willing to sell these couplers and I'm wondering if there is any interest in these. I have a nice 3d Printer that I can print them on demand. It take about 6hrs to print one, so probably I can do one a day.
I don't have a price set for that, but I'm thinking between $10-15 plus shipping.
I'm also working on Atari 7800 coupler for the original joysticks.
Here are some pics:
