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.

  1. Hello, I got the zerocam for this but that was obviously wrong of me. But i notice your camera has brown transfer cable but the original has white, so just wondered which camera you were using?

      1. Any chance I can get my hands on the STLs? I tried to purchase them from pinshape, but there is a problem with the site and it isn’t letting me buy it.

  2. Hello. Interested in your design, but it seems the second micro usb cannot be used, since the mounting hole is in the way.
    Would I be able to modify your design, i.e put this hole on the opposite side ? How difficult would that be ? TIA

  3. So i have another problem, the video is vertical like 1080×1920 instead of 1920×1080. Using Pi camera V 2.1? Any idea were i got it wrong, was thinking i could just turn the board 90 degrees but then the screw holes didnt fit.
