All the 3d files are github available in sketchup format. I downloaded them you can import them into cambam with a extension change. Make yours in metal if you have the resources to do so. Plan on polishing the components thou. Fuzzy yarn hangs on every rough uneven surface.
You can of course have the 3d parts printed online.. As I should have. I have spent months making my own 3dprinter to fit all my needs. If all else fails, throw time and money at it. I have not been bored, but not making headway much.
I am working out the bugs on the flat-bed afghan knitter. the carriage-cam plates that come with the ultimate sweater machine is crap. (due to the lead-lag feeding of the yarn and all the internal switching jamming) A better design would be a simple cam-plate with smooth flow, and a switching lead-lag yarn guide.

The google forum Gerard posted, I have some of the information I have discovered posted there now.
