Folding Table Hinge - V2

An updated version of folding table hinge. It's intended for a folding table that uses 2020 aluminum extrusions as the legs, and the locking pin locks the leg in either the open or closed position.

The update focused on stiffening the hinge by adding an addition mount point to the table, as well as additional features to the locking pin. The locking pin now engages the base directly on both sides of the leg, and an optional 'retainer' on the open side of the pin to further stiffen it when upright.

I designed it for, and printed mine from PETG, but going with a stiffer material like PLA should only be improvements in end results.

The different bearing sizes are for dialing in the fit on the inner bearings.
