Flip-down drywall anchor prototype (1/2" hole)

An idea I had and gave a quick try a bit ago. It's very much not a finished product, but I don't feel up for putting a bunch of time into developing it, so maybe someone else can have some fun with it. I cannot be blamed if it breaks when you try to hang up your $50,000 antique vase or child's hammock etc with it.

It consists of two parts - a base plug and a pivoting lever, with a piece of wire or similar holding them together. The lever has a heat-set insert in it to accept an M3 screw. The lever is snapped into the track of the plug, moved to the top and tilted flat, with the wire threaded through the hole on the base of the plug. The whole assembly is pushed into a hole (half inch for this version) and the wire is pulled which (hopefully) tugs the lever down flush with the inner face of the wall before slipping out fully, leaving a threaded hole hidden in there to accept a screw.

This obviously could be improved in a lot of ways - there's not really anything other than the grooves on either side keeping the lever in place. Some sort of ratchet like a fliptoggle would be helpful. Maybe a pull string that has hooks on it and some matching hooks on the base piece so it acts like a zip tie.

I have tested this a little bit, it's currently holding up a hanging clothes cubby thing, I will report back if it ever collapses. Worth noting that in the process I accidentally lost one of the levers, and it will remain in my ceiling for an indeterminate number of years. It does NOT like when the wall cavity is full of insulation!

There is a thread-in version commented out in there as well.
