The units.scad file comes from (IIRC) the MCAD library and has some
conversions between inches & mm and suchlike. The "useful sizes.scad"
file has similar dimensional odds & ends I've collected along the way.

Mercifully, 1 OpenSCAD unit = 1 mm of plastic.

I find it's easier to design models that are symmetric around the origin
(or at least oriented for easiest tweaking), then orient & position them
as needed for printing. Most things have several parts, anyway, so the
complete model never gets printed.
