you’re more than welcome to produce these in stamped steel or injection molded plastic if you see an opportunity there.
I agree that the price is high, and there might be some adjustments that I can make to the design to bring my cost down. I have very little time to devote to design work at the moment so I haven’t had much of a chance to see where the design can be optimized. Either way it’s unlikely that the price could be brought under 100USD while using 3d printing with urethane as the material, which I believe is important.
Anything is possible if the demand was enormous. But selling a few here and there doesn’t warrant massive investment into up front production costs. Obviously, if the price of the items was drastically lower, the demand would probably be a lot higher, but still not likely to be high enough to mass produce these.
