Parametric Lego Robot Treads

thingiverse

This is part of a set of fully adjustable Lego compatible robotics components. This post is for parametric Lego compatible TREADS. (Necessary wheels are a separate component, available here: https://www.thingiverse.com/thing:2417830) (Each wheel is its own customizer.) Files Included: *An openscad file for generating any length of tread with any desired tread pattern. When customizing wheels and treads, they must have the same number of teeth to fit perfectly together. To make a tank tread, use the attached excel calculator to determine the ideal number of tread teeth. (Alternatively, you can try trial and error!) The wheels should be printed in a hard material like ABS plastic. 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.
