Mathematically speaking, this wheel is a tetradecagonal prism. This construction, which uses a mix of units made from 1:√2 and 1:2√2 paper, isn’t mathematically exact but it is close enough for practical purposes. When designing this model, I wrote a short Scala script to find polygons whose radius could be approximated with good precision using modules folded from paper in easy to cut proportions (the ratios had to be built from small integers and √2).
