I can create a customized version of http://www.thingiverse.com/thing:94018, using the Customizer tool to adjust settings such as clip front length and tooth spacing to my preference. The instructions for using the options include clipping at front length, using write/Letters.dxf font, clipping with a specific width and height, applying offset, setting text as Mario, and so on.
