Befenybay Black 3-Way 2020 End Corner Bracket Connector

The Befenybay corner brackets were a small part of the Custom Rock Tumbler, but they helped make the aluminum frame feel like a real machine instead of a pile of parts. The tumbler needed a square, sturdy frame to hold the motor, rollers, belt path, and PVC barrel in alignment.

These connectors made that frame easier to build and adjust. With extrusion, the nice thing is being able to assemble, test, loosen, shift, and tighten without starting over. That mattered on this build because the roller spacing and drive setup needed practical tuning.

They are not flashy, but this was exactly the kind of hardware that made the larger rock tumbler feel more capable than the failed store-bought unit it replaced.
