Spoked wheel from Sturdy Edge Modules
A fourteen-spoked wheel made from my Sturdy Edge Module (StEM). This is a tetradecagonal prism but is round enough and strong enough to be able to roll.
Paper proportions are 1:√2 and 1:2√2. While the construction is not mathematically exact, it is quite close and the paper aspect ratios are easy to obtain from A4 paper.
