This is remix of the Case for Raspberry Pi model B+ and 2 B for raspberypi3 , the only change is that the LEDs on the raspberrypi 3 are on the other side of the board, this design takes that in to account.

You can use the openscad file to add holes for the camera, for GIPO and sd card.

Its the only case I found that snaps perfectly and took in to account expanding of the filament due to the heat.

To use download I suggest you use both top and bottom, since openscand adds a small shift to the fully assembled parts.
