Whatchamagear

Make your own _Whatchamagear_ in the Customizer (open in Customizer) or download the attached STLs.

_Part to print_ selects what to display in the Customizer (all parts, first gear, second gear, holder or "show assembled").

You can tweak the following parameters:
* axle diameter
* gear thickness
* eccentricity (see below)
* number of teeth per lobe
* number of lobes (see below) for each of the gears.

The attached STL files were made using the following parameters
axle diameter = 30 mm
gear thickness = 8 mm
eccentricity = 0.25 (0 for circular gear, 1 would be an unbounded shape)
number of teeth per lobe = 9
number of lobes = 3 and 4, respectively

Happy tweaking!

**Updated** September 27, 2019: Increased distance between gears in "All Parts" view. For some gear geometries they were too close, so that the teeth overlapped.
