push button fidget toy

Was trying to emulate the bistable CMU design, but in a smaller formfactor. It didn't quite work and ended up being just a normal push button. The thickness I set this is to 5mm. I then used http://svg2stl.com/

But a key thing I observe when making this when using PLA filament:

* The spring walls must be less than 1mm (Around 0.5mm). 2mm is too thick and it will not flex.
