Simple Drywall Screw Hanger/Hook/Mount (Parametric)

The typical hooks and hangers I see are too complex for what I need. This is a simple shell that makes it nicer to hang things off drywall screws. The base makes these easier to print and increases the strength of the hook by making it harder for the screw to rotate under load.

For the OpenSCAD nerds:
I learned about children() while writing this script and wrote a timeline of the part as it evolves. This makes it easy to see how changing variables impacts the part from the earliest steps
