Drain Cam v2

Made from a 50mm water pipe bushing and two end caps. LEDs powered by 2 AA batteries and a Reed switch. One length of pipe was cut open lengthwise to form a sleeve around the bushing, inset is a small ball magnet that activates the Reed switch when the sleeve is rotated into the right position. Attached at the back is a spiral drain cleaner which allows to push the camera down the pipe and rotate it if needed.

I had to 3D print the battery holders as ordinary ones were too large and interfered with the camera body in the middle of the pipe.

I made the mistake of using polypropylene (PP) pipe which is almost impossible to glue, e.g. epoxy and superglue don't really stick to it, so it proved really hard to seal the thing. I ended up filling both end caps completely with silicon caulk just to be on the safe side.
