Raspberry Pi B3 case for Alunar M508

This case is specific to Alunar M508 and Raspberry Pi 3 Model B+. It might fit some other models but I only have Raspberry Pi 3 Model B+ so can't comment on others.

Idea came from: https://www.thingiverse.com/thing:2052064
also I used case designed here: https://www.thingiverse.com/thing:922740

I only modified bottom part. You can print top cover from original case design.

The result is great.
