OpenRC Tire Mold for castable Rubber Tires

This is a 3D printable mold for casting your tires.  Ninja Flex is expensive, and many extruders won't handle it, this is an alternative way of making your tires yourself.  You only need to cast one copy of the mold and you can cast all the tires you need from it. I use Oogoo for casting my tires and you can find the recipient here:

Have fun.
