Ray-Ban Clubmaster sunglasses

I had a project at school where we would design sunglasses so I designed a pair of Ray-Ban Clubmaster. I do not know if they can be printed with a 3D-printer so therefore I upload them here so maybe someone can test and then comment on what I need to change.

If someone has 3D-printed a pair of glasses before you are welcome to give me some tips on the design to make it work.

Everything is designed in AutoCAD 2013 (MAC)
