Optimized snap connection

This is a study to optimze a snap-on connection for PLA. The geometry is desigend so that stress is more or less equally distributed over the geometry height.
The top is designed to apply constant pressure so that there is no play between the parts.

The design is independant from the height (Z) and the distance between the two sides.

Fusion 360 and Step files are included so you can use the design in other designs.
