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
**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.
