Reuleaux Planetary gear

Time ago, I've found a video "Reuleaux ball bearing: does it work?" Yes it works, but because the flat roller elements does not stay in position, it interlocks. So, my idea was been to make it in gears.
- Print this:
should be easy to print. You may have 3 reuleaux or planet elements each.
- What's new:
Math art model with base and crank. gear library follows the idea of gear cutting but is completely rewritten.
This is fully published in source files and opensource.
- what's not new:
Idea of gearcutting. I have seen this at user:parkinbot.
This is not a remix or copy. Maybe it is a parallel work.
- how to use the openscad design:
Because of long render times, this is a multistep design. for eample, load _sun.scad first, it will generate the gear shape. Export the render result as _sun.stl. Then load sun.scad. This will generate the final result sun.stl; and so on.
Reuleaux gears are combination of normal gears, there is no mathematics for this extraordinary shape.
gears.
