A simple parametric script for cookie cutters.
I used the font Kreon Bold from http://www.thingiverse.com/thing:13677 , any of those fonts should work.
I have included stl-files for most letters and numbers.
note: There seem to be a few issues with certain letters: b, d, q, p and P give errors.
- scale if needed
If you want a different character or another font, you can edit the openscad script. You can download additional fonts at http://www.thingiverse.com/thing:13677 (make sure you have the latest version of openSCAD!)
You could also modify "module shape" if you want something other than letters or numbers.
