Super Tiny Toggly Fidget Buttons

This is a remix of the excellent fidget buttons by 3D Printy.  Goal obviously
was to make them as small as possible.  If printed correctly they are very snappy like
popping bubble wrap.  All print orientations are already set.  For the spring I print in 0.1 layer heights so it ends up exactly 2.6mm
thick.  This is important to make the buttons snappy and also to hold the case halves 
together.  All Other parts I print 8 walls 0.16 layer heights 98% infill.  Honestly the pins for the buttons 
could probably just be cut pieces of filament.  I did not try that but it should work and be stronger
than printed button pins.  The buttons I chuck into a power drill and polish with sandpaper of different 
grits until they are very shiny. Enjoy.  youtube video for demonstration https://www.youtube.com/watch?v=24MVARwZ-qU
