An individualized edition of http://www.thingiverse.com/thing:47842 was created with the Customizer (http://www.thingiverse.com/apps/customizer/run?thing_id=47842). For this specific project, the tool height was set at 5, a message measuring 8mm was engraved using the "write/Letters.dxf" font, and an 8mm nut was incorporated with an 8mm tool length.
