You will need Fusion360 for the parametric file, which is provided under the downloads. The file is robust, but you may “break” the model if trying to create a wheel at the extremes (very small or very large).

The print profile provided is for a 50mm wheel, that is 12mm thick, and uses a 6.35 (¼") bolt for an axel. Feel free to add your own print profiles of different size wheels you create, but please make sure you label them so others know what size it is.
