Raspberry Pi 2 model B / 1 B+ snap-together case

This is a subtle remix of the modular Raspberry Pi 2 Model B / 1 Model B+ case by aurelius.
The only difference is that the tabs have little snap mounts in them, which makes the top and base snap together nicely so the case won't come apart easily.

And to make it slightly easier to pull out the microSD card, there is an alternative base model (v2) that has a slight recess around the SD card slot.

In case you would want to adapt one of the other remixes of this case to have the same tabs:
**For the top part:**
Create four spheres and scale them to X,Y,Z dimensions of respectively (1.0, 1.6, 1.6) mm. Taking RaspberrySnapCase_base.stl as reference, position the spheres at (±28.5, -39.0, 11.5) mm and (±28.5, 41.47, 11.5) mm, and join them as such with the the lid when it is aligned to fit the base.
**For the bottom part**
Create four spheres at the same locations as
