I need to design a fixture that holds two rods at 90 degrees to each other. It must be something that is very cheap to produce. I'd love to use a standard plastic tee but they don't produce 5/16" tees.
I imagine something like a plastic cube with two thru holes drilled perpendicularly to each other. The holes are offset so they don't intersect. Size tolerance for holes and their relative to each other position must be no more than +-0.01"
How much such a mold would cost? Can I expect a Chinese manufacturer to machine these parts really($0.20) cheap if I order 1000 pieces?
