RC wheel mold

A remix/rebuild of http://www.thingiverse.com/thing:26279 I tried his design but modified it a bit, but given the fact that I do not have the source files and work in solidworks I started anew. The mold is designed around the 8 mm hex hole rim from the link.
Also I still only have a single tire design. But if you feel like it, any half round circle out diameter of 69.5 mm and a wall thickness of 3.5 mm and a design protruding will do I guess.
Work in progress, I'm currently printing these parts for a test run and possible a refinement.

So I like designing thread patterns for tires :)
A crosshatch similar to what Danithebest91 made only suitable for my molds and coarser.
Two different chevron designs one V shaped and one with a step between them. Unfortunately for proper printing I needed to add a little tabs to the chevron mold to support part of the print.
Only the trekkerband (which is a a wrong name btw) has been tested thus far.
