OpenRC Tire Mold for castable Rubber Tires

pinshape

This is a 3D printed mold for casting your own tires. Ninja Flex can be pricey, and many extruders struggle with it, so this DIY method lets you create your tires from scratch. You only need to print one copy of the mold and cast as many tires as needed from it. I recommend using Oogoo for casting my tires; you can find a recipe online at http://www.instructables.com/id/How-To-Make-Your-Own-Sugru-Substitute/. Oogoo sets in under 10 minutes, making printing molds an efficient way to produce multiple tires quickly. For added realism, add a few drops of essential oil to the mix; within a few days, your object will have a scent that's not vinegar.
