Updated Rainberry Design

After purchasing Prusa i3-mk3 3D printer, I could now do more design iterations and improve the Rainberry camera case design further.

Both Pi Zero W and Pi 3 cases are improved with 3D printing tolerances for appropriate fits and top part radius. Additionally, a seal for power cable is now added to reduce water ingress from bottom part of camera.

A different glass of 18 mm and 1.5mm thickness is used in this design, as previous 17.9mmx1.2mm glass is now discontinued.
