Because my laziness knows no bounds, I decided I need a "Productive Susan" on my work table for parts in use (if you aren't familiar with the original design, details can be found here or in my profile.)

Similar to the original, the rotation is provided by a couple of tapered roller bearings, but this time both sides are sandwiched in the base and it's compressed with a fastener up through the 'tree'. Full build details are at the same spot linked above.

Design files are on OnShape here....sorry in advance if you choose to dive in, it's not exactly to 'best practices' :)
