Fracs

Fracs are the spherical gears used to create fractal gearing mechanisms, and their counterparts are the base forms utilized for construction by boolean operations (Intersection) on spheres and rotational combinations of a 1x1 base generated by spheres. Files surnamed Fibonacci are using Boolean operations on a 1x1 base which is generated by the revolved surface using the Fibonacci spiral. Fracs are useful in numerous types of mechanisms such as robotics, engineering, farming, cycling, toys, machines, and other power-bearing and transmission applications. Along with other numbered fracs, these are used to complete power-bearing and transfer mechanisms with proper working arrangements. Models exist for the 1x1 all the way up to 21x13 frac. The 2-inch diameter in the file names is an approximate diameter of the bounding sphere but most are larger. This means that the frac forms are generated by boolean operations on a 2-inch base sphere, ensuring that the scaling is consistent throughout all models. The north and south poles have pivot points which are ideal for holding, and there are limited ways to hold the asymmetric fracs. https://youtu.be/gNEJtigdsB0 Along with other creations already uploaded to Cults, here are some intriguing examples of what you can build with these fracs: https://www.youtube.com/watch?v=7Tv-aUC6lpM https://www.youtube.com/watch?v=od4LXTEEpik This is 100% open-source so that you can use it in any way you like, including commercially in your own products.
