Conical Roller Bearing

This is a fully parametric conical roller bearing.

Inspired by [this design](https://www.thingiverse.com/thing:2375124). My design is a bit more material efficient and has improved geometry to allow for a much wider array of possible sizes. The rollers' height and angle will change according to the number of rollers and their size. The housing is also 100% equation driven (height, width, race angles, clearance) so should not need any direct adjustments. I do not recommend playing with anything that has a trigonometric function.

When suitably glued (I just use superglue), they can handle a surprising amount of force, both radially and axially. The "glue channels" are designed to allow you to assemble the bearing first to ensure it works how you want it to, then drip a *tiny* amount of glue into the channels. The channels allow the glue to penetrate into the inner surface without the risk of making contact with the rollers.
