OpenSCAD Etching Tool

This is a very simple tool in OpenSCAD to etch pictures onto anything for printing.

Put it in a directory with the .stl file and the image you want to etch into the .stl file.
Resize and move it around until you get what you want.
If I can do it. Easy.

Example included is a cover for a shot glass.
Other images of other things I etched.
