3D printers have been a boon for rapid prototyping, but they’re not without their foibles. Whether it’s a faulty extruder, the piece sliding off the bed, a slipping belt, or any number of other errors, one might walk away from a print that’s begun and come back later to find something he/she had not expected.

Luckily, sometimes these 3D printer fails┬ácan come out looking quite interesting. Here are 12 3D printer fails┬áthat went right past bad and back to good again. If you’ve had similar experiences, please share them in the comments section.
