Any Size Wrench Generator

I created a wrench generator in OpenSCAD that makes:

metric or SAE/imperial sizes or custom sizes in both millimeters or inches
box end or open end
6 or 12 point
configurable handle length
configurable thickness (z-axis)
configurable wall thickness to adjust strength
adjustable tolerance for bolt clearance and/or printer anomalies
with or without size label with fractions if applicable (non-standard fractions will have decimal labels)

I chose to make both ends the same size and each end is customizable in its own way. i.e. one end can be open or closed, the other end can be 6 or 12 point, either end can be round or hexagonal shaped and configured independently.

I posted some example stl files to show some script features as well (created just prior to my last couple code refinements). I recommend using the OpenSCAD script to generate your own.
