So the current plan is going to be different to how the nexus stab adapters were done. I originally had them 3D printed using material jetting and got them for ~$7/set, not too long after the GB prices shot up to ~$60/set, which really destroyed my hopes of ever being able to support them again.
Current plan is to see if we can possibly get them injection molded, trying to look into how viable this is before anything else is said, I don't want to get anyones hopes up in case prices aren't able to be brought down.
