Lazy Susan BBBearing (Open Center)

Sometimes you want to pivot around empty space... This is a bearing with an empty center.

You can choose how big a hole you want in the center, the size of ball bearings (default is BB ammunition) and the size of bolts you want to use. The rest is automagic!

This is designed to be bolted together.

The STL provided is a 20mm center hole, M3 bolts, and .177 caliber BBs as the bearings.
