WTF cow !
So if anyone is interested in mass producing it, contact me!
Cleaver idea ... and low tech. Why aren't YOU
Source out the materials, fabricate some tooling, hire a high school kid to assemble it, get a DBA, place an ad in a couple of car rags ... and you're in business.
The thing doesn't have to be an injection molded, double-throw-me-down, high-tech production to determine the interest in the product ... and if there is a larger market, the low-tech version will pay for the tooling.
SCREW the patent!
Think guerilla manufacturing here cow. Hit 'em had and fast. By the time someone tries to rip you off, you'll be on to the MarkII model. And if interest (sales) in the product is less than what you anticipated, just cease operations, and rack it up to experience.
In the early nineties, I sold six thousand PAIRS of ergonomic knobs for R/C transmitters, and every one of them was cast urethane (from a hand-made pattern, and RTV tooling) with a brass thread insert. I sold them for $14.95 a pair, and the margin was acceptable. The next thirty-five thousand were injection molded, and the margin was considerably better.
