I liked the way the original worked, but had a hard time finding hardware. I redrew this one to accommodate a larger screw head. This will fit a standard flat head hex countersunk 6mm now. I attached the Solidworks drawing, in case you need to tweak it. So far it seems strong enough. Time will tell.
