Alphabet Cookie Cutters

After literally tens of minutes of of development, I think I have a good process for making alphabet shaped cookie cutters (or any shape cookie cutters for that matter)

To build one of these in sketchup:
- Make a shape and extrude it to about 1.5 or 2 cm (3/4")
- Use the offset tool to make 2mm (1/8") line around the perimeter of the shape. Holes in letters are problematic, you may have to draw by hand.
- push the new smaller shape back to 1/8" less than your original extrusion. this makes a "floor" and "walls"
- sharpen the walls
- push "holes" in the base so you can get the material out after you cut

Note, this is an upgrade from my previous cutters, thing 6979
