Parametric Bearing (Fully Printable)

This is a highly customizable, fully printable bearing. It can be printed with a fairly low end printer (I use Anet A8) and still work because it can be cleaned up before assembling. It also doesn't require any supports and likely no raft/brims.

Obviously it doesn't spin as well as a bearing made of metal, but I think it is still good enough for light applications. Here is a video to see how well it spins: https://youtu.be/E3SVvrHNiLI

I haven't tested many parameter combinations (there are millions), but I've chosen default settings that seem to work pretty well. For other parameters take a look at the 'section' view to make sure things look ok before printing.

The latest version I've uploaded fixes some minor tolerance issues, and gives better default values for the customizer.
