Peter's new invention

I have a new invention I'm developing. I'm sharing how I'm doing it, how I came across it, what the next steps are, including a couple of parts the need 3D printing. I'm new at 3D but working to developing some capability using Shapr3D software.
Most importantly I want to show by doing why exposing your idea is not a bad thing: too many inventors get stuck in the patent and protection phase and don't have resources left over to actually pursue the idea beyond that!
Would love to see what you're working on and if I can help at all.
