Tire_Full_Text.scad

Update: Use https://makerworld.com/en/models/1012706-customizable-tire-for-pinewood-derby-trophy-remix instead, as it is the newer version. You can turn off

- Render_Rim

- Round_Tire_Bead

- Holes_For_Topper

to make it exactly like this one.

This is a parametric simplification of Troysterr's Tire_Full_Text.scad. 

The equation-based tired is rendered in red, and Troysterr's original tire is rendered in yellow. The photo shows how closely the equation-based tire matches the original, such that the faces intersect each other at almost every point.
