As nearly as I can tell, Google Sketchup is the wrong hammer to create a 3D model that you intend to produce with a 3D printer. It's not actually a 3D program, because it works with surfaces, rather than volumes, and it's remarkably easy to produce a model with missing / misaligned / incorrect surface facets. Such models simply can't be converted into a proper STL representation for conversion into G-Code. A quote from Sketchup Support that I used in a talk for the local ACM chapter (screen 43) sums it up pretty well:

SketchUp is not the same as Computer Assisted Design or CAD. CAD applications are designed specifically for representing concrete information, while SketchUp is for exploration and design of concepts and ideas (though you are not prohibited from designing models that are as concrete or accurate as those designed in CAD).

I think you've just discovered that on your own... [grin]

I’m still at a loss how to do this in SketchUp. I have the cookie cutter itself pretty much figured out, but the press is still a complete roadblock for me. I think you should become a master of SketchUp, not OpenSCAD, and then create a tutorial video showing exactly how to make a cookie press and send the video to me. Yep, that’s what I think. There could be cookies in it for you Ed. Be the hero. :-) Cristin
