mp3 player case for a tonuino mp3-player

This is MK3 and the first I publish. Had to get rid of some quirks of earlier versions. I bet there is going to be a MK4 and I'd love to get some feedback on where I can improve things.

The tonuino will be for my daughter and I'll have a case made of wood soon. For testing and quick use, I am going with PLA.
