Nice thing!
I love you guys in the U.S. :-)
You have a 19mm penny, but 4-40 inch screws with .5inch in length. :-D

penny_gun.stl sliced incorrectly with slic3r.

Yeah I'm aware that there are some minor holes in the mesh. If possible you should consider slicing it with skeinforge or similar slicer. I used SFACT which was capable of fixing the mesh on the fly.

Sorry. I designed this in Google sketchup which isn’t the most robust application for drawing manifold solids for printing. I think the problem here is that the curved surface around the penny slot somehow drew partially inside out and didn't correctly reverse when I tried to fix it.

I upload
ed a slightly modified version which fixes some of the old errors but some of holes still exist.

Very nice; I'll be bringing a few of these to work Monday.
