Ball Bearing Race Generator

cults3d

Some code I whipped up to generate bearings. Originally specifically for use with Airsoft BBs as balls, but configurable for any size ball. This is a work in progress. If you print a bearing and have any input on improvement, let me know. 2019-03-07 - Updated scad file to improve poly count and introduce slight tolerances in the race size, as it was extremely tight and did not actually roll, though it did assemble properly, which I consider a win for a theoretical design. 2019-03-08 - Rebuilt the base extrusion source to allow for a dynamic race placement depending on a user specified number of ball bearings. The more balls, the closer to the outer race the ball channel will be. If a user specifies too many or too few balls, the model will be generated with the max or min, respectively. If a user specifies a ball too large to make sense with the other dimensions, an error is given instead of a nonsensical object.
