3D Printing with different colors is fun! We've put together our favorite iOS app icons and made keychains out of them for you to 3D print your own!
If you have a 3D Printer capable of multi-colored printing, these geeky keychains make for a great experiment. We're using the "Change Filament" option on our MakerBots to get two-color prints. We're using glow-in-the-dark ABS material for the top level to make them extra awesome at night! No rafts or supports needed.
