Using a flexure spring and an over-center mechanism to create the classic toggle switch in an interesting way. WobbleToggleSoft.stl has a thinner spring for a softer click and is currently my recommended version. WobbleToggle.stl is the original version and WobbleToggleLoose.stl is the original version but a bit looser (0.3 mm clearances). 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 (which has relatively high friction with itself). Update 18 July: made some minor changes to the geometry to improve printing and feel. Update 19 July: made a small chance to the spring to reduce strain in the center. Update 23 July: added thinner spring version
