Printable ogoo mold for making RC car traffic cones (pylones)

This is a printable mold for making traffic cones for RC cars out of ogoo. These are great for marking a course for RC cars. The example molds in the photos are 80mm at the base and 30mm tall and we use them for racing with an 1/18 scale RC car.

Ogoo is a silicone caulk based DIY molding material. It is cheap and easy to use, see: http://www.instructables.com/id/How-To-Make-Your-Own-Sugru-Substitute/ Read the safety hints on the cartridge and make sure you understand the required precautions when working with silicone caulk.

The scad file is supplied and is fully parametric, you can make all kinds of shapes. A few examples are supplied as stls.

I did not make the interior hollow because that would just make the molding process more complicated as it would require a (printed) mold core. After all, ogoo is really cheap, with the example molds I could make 3 cones out of a single cartouche for just under 2 EUR. Besides, the filled cones are quite heavy, which is good (in comparision to bought cheap plastic cones which fly around if there it's a little bit windy or if they are touched by a cornering RC car).
