Geohashing cookie cutter (Q41781)

This is a geohashing cookie cutter, see the official page for details: http://bit.ly/ghcookie I have designed the first version (ghcookie.*) with the Custom-Cookie-Cutter-Generator by guru (thing:3433, how can I link to it?). Then I've improved the shape a bit, still using the same tool (v2, ghcookie2.*). Because I was still not completely satisfied with the result, I used some shell script to convert the CookieCutter custom format to an SVG path and used Inkscape + OpenSCAD to rework it and create v3, which prints much cleaner. Finally, after having made the first cookies, I wanted to make an even better v4, with an additional accessory to hold the cookie down while the cutter is lifted. This is now reality and I was really pleased with the result. I've left all the older files for your reference, but if you intend to print one I suggest you focus on v4. This work is in the public domain, there may or may not be some restrictions on the geohashing logo itself.
