This is an example of my problem generating a hole. I was hoping to print this, and not drill it out, but the skeinforge preview implies otherwise. I have included the blender file as well as the STL file generated with blender.I hope someone can use this to debug software or enjoy a funky bead, wheel or device feet. It might look really cool in PLA.Please see the discussion thread in the makerbot group to help with your design problems like this. http://groups.google.com/group/makerbot/browse_thread/thread/1cf0e94ef85df526
