Raspberry Pi (2b, 3b & 3b+) cat, bunny or unicorn slim box V4.3

I know, there are already a lot of existing cases for Raspberry Pi… I just really wanted to create mine ! :)
After making this one : https://www.thingiverse.com/thing:1405805 I wanted to work on a more "slim" design. Also, I made an opening on the top to allow some ventilation, so why not make a nice one. With this model, you can choose the cat or the bunny shape, as you wish (bottom is the same for both).
Warning : this is a design for general desktop computer use, there are no opening for GP
