This is a general purpose clamp for use with the honeycomb storage wall.

There are no supports required, just make sure that bridging is enable to easily print the base.
Tolerances are tight, especially on the base that meets the clamp. I'm working on an edit so the tolerances aren't so tight so check back for updates if you are having issues with it.
