Parametric Lego Robot Treads

thingiverse

This is part of a set of customizable Lego compatible robotics components. This post is for parametric Lego compatible TREADS. (Necessary wheels are a separate Thingi here: https://www.thingiverse.com/thing:2417830) (Thingy's are separate because each is its own customizer.) Files Included: *An openscad file for generating any length of tread with any tread pattern you want. When customizing wheels and treads, to make a perfect fit they must have the same number of teeth. If you want to make a tank tread, use the attached excel calculator to determine the appropriate number of tread teeth. (That or trial and error!) The wheels should be printed in a hard material like ABS. The treads must be at least semi flexible. The TPU linked below works but is a bit slick for mini-sumo and is tight for stretching. The TPE filament makes ideal high flex high stretch treads.
