Fob Protection Case

This is a improovement of the simple [Car Fob Protection Filled](https://www.thingiverse.com/thing:4787244).

The simple cover broke often at the key ring. So I designed a whole case. It is sturdy enough to prevent unwanted opening of the car and windows, but it is soft enough, so you can still press through the case to open the car if you need to.

I had some versions which had layer separation after a while. But in my last print I used a thickness of 1mm and used overextrusion with a 0.4mm nozzle: I configured a nozzle of 1mm but still printing with the 0.4mm nozzle. This version still hold and I thing layer separation is not that big of an issue anymore.
