I've been thinking about it, I think I can approximate it with tube and sheet metal. Maybe next week I'll get some more time on it. I looked into 3D printing it but I think it's cost prohibitive (like 2-4k) which is a bit more than I'd be willing to spend. Traditional sand casting or wax would both work but I can't do that. I could probably print up moulds.

Anyway, I'll think about it a bit more.
