Fracs
All the fibonacci (golden ratio) numbered and Odd "Fracs" from the Fractal Gear creation diagram, as well as their complements ("??"x1). Fracs are the spherical fractal gears used to make fractal gearing mechanisms, and their complements are their base forms for boolean constructions by rotations. Along with other numbered fracs are used to complete mechanisms with proper working arrangements. There is the 1x1 all the way up to 21x13. Higher numbers are not practical except maybe for a gigantic megalithic frac, but not sure why anyone would want that, unless maybe you desire to build an elevator to the moon.
The 2 inch in the file names is an aproximate diameter of the bounding sphere but most are bigger. It means that the frac forms are generated by boolean operations on a 2 inch sphere, and it insures that the scaling is the same throughout all the models.
The north and south poles have pivot points which are great for holding, and there are not many ways to hold the fracs.

Along with the other creations already uploaded to cults , here are some interesting examples of what you can build with these Fracs:

These Fracs are %100 opensource and very useful in robotics , engineering, farming, cycling, toys, machines, and whatever.
Supports needed on the 21x13, 13x13,8x5,5x5,5x3 Fracs printed whole. To avoid supports ,print in two halves then glue together and the overall print quality will be better and faster. 21x1,13x1,8x1,5x1,3x1 can be printed whole without supports with the flat side down.
