Remix from jakejake's Hand-Screw Clamp https://www.thingiverse.com/thing:2403756
I extend the jaw by 10mm, add 2 flanges so the clamp can stand up on itself at horizontal/vertical position.
I also "patch" the the narrow gap of original design. Narrow gap is still there, serve as forced-wall reinforcement structure, just hide below the surface.
You can also use other good remix part such as:
