UPDATE I have added a second version of the cookie cutter with the floating cube removed, as well as a hole to use as both a handle and means of removing any sticky fingers! Disregard issues with floating cube mentioned below.
When I saw everyone making cookie cutters I had to come up with a funny one. Great for sweet sweet (literally sweet) vengance! Also great as a gag gift! Pattern cuts with gaps so when the dough expands it makes realistic looking fingers and knuckles.
Will print in as little as a 4x4x4 printer, and design can be expanded for bigger printers.
Note the cube in the middle of the finger, this is an error and the way my software works i could not go back and delete the whole thing without doing the whole trace over again, so you may erase it using your own means, but I just went ahead and printed with it and had no adverse effects.
I used Creo Parametric to trace an image of a middle finger, and then created an extrusion around the outer most perimeter. After doing that I saved the STL and loaded it up in matter control, enlarged it as best I could to fit the printrbot simple, and pressed print!
