HF Harbor Freight half inch pipe clamp covers from approx 2005

These covers should be printed in TPU, and are designed for a Harbor Freight 1/2" pipe clamp from about 2005.  I coded these in openscad, some of my first, so they could be better.  I did have claude.ai clean-up and comment the code for better usability.  The difference between 2005 and later models is that the non-screw side flares out in width away from the pipe.   I also note that my clamps are stamped "japan" on the non-screw side, which may be another indicator.
