Trailer cap

Fed up with the cover over your trailer becoming a pond in the rain? I was. You probably weren't. I made this ridged peak to go on my trailer. It creates a little rake to the roof and stops the water from pooling.

These joints are designed to be an easy push fit with 21.5mm waste pipe available from all good UK plumbers (such as http://www.screwfix.com/p/overflow-waste-pipe-21-5mm-10-x-3m-pack-of-10/18180). The OpenSCAD file is present so that you can tweak the dimensions. The edge pieces simple slide on to the side of the trailer.

The ridge pieces have a down pointing prong so that you can prop the whole thing up with more pipe if you choose, but I haven't found it necessary.
