No, I'm not looking for something submersible. Just a case that can stand the rain. It will be place under a roof, so it won't be in the full rain though.klricks wrote: ↑Wed Aug 02, 2017 1:22 pmAre you looking for weather proof or submersible? I doubt there is something specifically made for the RPi.
Here is a generic box: http://www.mcmelectronics.com/product/2 ... UMQAvD_BwE
If you are looking for submersible then there are many camera / video cam enclosures which could be used. Google........
Thanks for your reply. Hadn't thought of placing it in a general case (or something made for other equipment). I was just looking for a genuine Pi case, but this might be an option.PiGraham wrote: ↑Wed Aug 02, 2017 1:51 pmPi Zero should fit in most GoPro style underwater housings, but I think Pi3 is too big for that.
It is a cheap option though

You could try a similar type housing for a compact camera. This one is for a Sony Cyber shot DSC W320

You can get plastic enclosures made of polycarbonate that have IP67 sealing and transparent lids. Those would work but it would be better to look through a glass window rather than polycarbonate.
This one is ABS with clear transparent lid and IP65. Others in the range are polycarbonate have a smoked transparent lid and IP67.

Look for similar that has IP67 and a clear lid.
Thanks a lot! I will somehow have to let the power cable in, so a little hole on the bottom could serve both targets...rurwin wrote: ↑Thu Aug 03, 2017 11:51 amBe aware that a case can be too waterproof.
When opening boxes that have been outside for a year or two , one often finds a significant quantity of water inside. It isn't because they have leaked in the rain, it's more insidious than that.
During the day the air is warm and warm air expands and can hold moisture. During the night the air cools. That causes a partial vacuum inside the box which pulls in extra air through the seal from outside. As the air cools further the moisture it contains condenses out. In the morning the box warms up again and the air expands and it pushed out through the seal. The box is waterproof and so the water can't get out. Every day just a tiny bit of water gets into the box, less than a drop a day. But after years you can end up with anything from a teaspoon to half the box full.
It can be a better idea to put a small hole (say 1/8") in the bottom of the box to allow water to get out. Although that might lead to more corrosion since the inside will be exposed to more air-borne water. You might get condensation on the circuit board in foggy conditions. The alternative would be an air-tight box.
Chances are a 3D printed case won't be fully watertight, especially at pressure. You may be able to make it watertight by painting it or coating it with epoxy.
An SLA printer might produce watertight structures but from what I've read FDM printers make structures that are inherently pours because of the way the plastic is fused. I expect powder fusing types have similar issues.
