Today we managed to finalise the design of the 2 dog water tight doors, which are to be 3D printed. With a little bit of testing and a few different designs which mainly are the size and thickness of the doors, I have finally chosen one design.

The final size of these doors are 14mm high by 7mm wide and just a fraction over 1mm thick, so as you can imagine these are quite delicate.

The image below shows the final design.
