We’ve seen 3D printers make tons of things, from the novel to the useful, such as prosthetic limbs. Well John Mabry of Teague Labs wanted to see if he could make a completely functional object from 3D printing which could be put together without any tools, and this basically resulted in the pair of 3D printed headphones pictured above. He used a Makerbot Replicator to create these headphones and he even posted the schematics and instructions on Thingiverse, should anyone wish to replicate these. He dubbed them the 13:30 because apparently it took him a good 13 hours and 30 minutes to create them. Now we highly doubt that these headphones are of audiophile quality, but we guess the novelty of being able to print headphones in any design you want is pretty appealing.
