Randy, any plans for a vacuum-molded 3D version of this? I'm not in the market, but it was something that occured to me the last time you had shown this. And now that you've got the coin buttons, you wouldn't even have to worry about painting them, outside of a dab of silver on the lock, and the customer can do that with a small bottle of Testors.
I don't know if I would call it a plan, but this was modeled in an engineering program so I have the option of providing it to a vacuum former. I am aware of at least one outfit not too far from where we are that does this kind of thing inexpensively for packaging purposes. I may send them off an email to see what they can do.
The issue is finding one that can do them for less than a real steel coin door costs. Tooling will probably be the large up-front cost that would need to be factored into the sale price. If I sold 10,000 units, this cost would be negligible, but for some reason I can't see that happening

The other challenge may be finding a reasonably priced material that has that "powder coat" look. There would also need to be final machining performed on the part, again adding to the cost.
