That'd be nice, but even low volume run tooling would cost $2k+. Better have a lot of buyers. If I can't find one, I'm going to get crafty and repair the one I have. Fiberglass / bondo and what have you.
Think they were injection molded or formed? I have an almost perfect one but would buy to support the cause. I would say most that I have come across are damaged in some way. There is also a metal version used but I haven't seen very many of those.
