Bora/Harbor Freight Parallel Clamp Glue Cover (thinner)

This is a remix of https://www.thingiverse.com/thing:7104653/ - a copy of tht STL is included here because the original is marked "WIP" and this code depends on that exact version of the model.

That version worked okay but was way too thick to slip onto and off of the clamp bar easily. Starting with LaupCerli's STL I thinned the sides and added an optional ledge on the top. This. version slips on and off more easily.

Included is the OpenSCAD source for the modification so that you can make the cov er any length and adjust the thickness. This may or may not work with the thingiverse customizer.
