When I wasn't posting 'off topic' comments right here I was with my brother out in the garage developing "the next best thing". (that's not an advertisement)
After a few changes and a bit of questionable welding (aka fast) we did some testing and even filed for a patent.
While my skills in Tinker cad
are noteworthy they are of little use in the world of industrial design and manufacture. These file types work well for 3D printing etc, but are the equivalent of being in a chess club and only knowing checkers.
It appears there are non-contract CAD designers in the area(craigs), but I thought I'd cast a line in my favorite fishing hole and see if I can get a nibble, a bite, or maybe get pointed elsewhere.

While there are up to a dozen parts in total. most of them are little more than a cylinder or a screw etc.
The main component/s have a form similar to that of a door hinge with some modification to the overall shape, and the requirement that the hinge be tight enough that it is under permanent tension. (like a stuck hinge in both directions)
example below - (not the design)

______________________________
I hand drew the drawings that ended up being used for the patent filing. (didn't expect to use them for that)
Those drawings, other information and a prototype can be provided to whomever does the work.
Ideally we'll find someone who is available both now and down the road.
Someone that could push me in the right direction should I wish to develop my skills with 3D CAD design would be even better.

...So there it is.
ask questions. I'll reply later.
