Half-S half-square hook for jetted bathtub panel

This is a hook with a squared top and a curved bottom for holding up the panel on the side of a jetted tub.

The parameters in the SCAD file are fairly self-explanatory. The 'height' parameter determines the distance between the bottom of the top hook to the top of the bottom hook.
