Wobble Toggle Fidget Switch (print-in-place)

Using a flexure spring and an over-center mechanism to create the classic toggle switch in an interesting way.

Shouldn't need any lubrication, but like all mechanical prints, it can benefit from a little oil, wax, or soap in the joints, especially if you use PETG (because it has higher friction with itself).

Update 18 July: modified a couple pieces of the geometry to improve printing.
Update 19 July: modified spring to reduce strain in center.
