Ten commandments of 3D printing

thingiverse

This large key chain features a set of commandments and principles about 3D printing that you may accept or not. If you don't like these commandments, create your own using the rotating rings keychain. The outer rings are fairly loose, meaning they're meant to be taken out and in. Contents from outer to inner ring: * TEN COMMANDMENTS AND PRINCIPLES OF 3D PRINTING * Calibrate well for the first layer * Keep an open mind and be creative * Create supportless models * Honor other ideas and designs * Create assembly-free models * Learn from others * Make customizables * Share objects * Share code This thing is also a test of endurance for your 3D printer. So far, I've only tried two medium-quality prints with 0.15 layers, requiring between 13 and 14.5 hours of print time. A low-poly version is included, along with a smaller version that has more rings and a higher resolution. The text on this version differs from the original (see source below).
