This is very highly customizable wheel in the way of an OpenSCAD file with 46 parameters that provides a limitless set of combinations and wheel designs. I affectionately refer to it as "One Wheel To Rule Them All."

It can be wide, narrow, big, little, fat hub, skinny hub, no hub, through-hole, servo arm mounted, chamfered, multi-tire, modeled tread, optical encoder-slotted, and more. It even accommodates stretched o-ring tires. It just can't be square, because my sources tell me that won't roll well. The code is extensively documented, and traces out helpful information about the geometry of the wheel/tire, as well as encoder slot metrics (e.g. each rising edge is 42.42mm/1.67in in travel).

It includes twelve standard tread patterns (all configurable in often surprising ways), eight core spoke patterns (also highly customizable), configurable support for o-rings, bands, and optical encoder timing slots (directional and non-directional), and a lot more. Plus, Iâ€™m still adding features as I think of them.

The images show most of the core…
