Push-Push Latch Cardioid Up Down Button

This is an up-down push button with a mechanical latch based on a cardioid cam.   It can be adapted for a variety of uses.  For example, I am integrating it into a television remote control caddy wherein I will push the device to release the remote and replace it by pushing to a hidden position.

The model also demonstrates one of a number of the mechanisms (in this case, a cardioid cam) on which such push-push buttons may be based.  

I printed with PETG for all components and used 0.20mm slicing.
