3D PRINTING CONTEST
Calling out to all makers, designers and tinkerers, this is your chance to take part in our biggest 3D printing contest ever! Show us what this exciting new technology inspires you to create. Share your 3D models, projects with 3D printed parts, homemade 3D printers, and anything else your 3D printing-loving brain comes up with in the 3D Printing Contest.

In partnership with 3D Hubs, we are giving away 13 (!) of the best 3D printers chosen by their community of 13k 3D printer owners. Enter the contest to win a BEETHEFIRST, Kossel Mini, Lulzbot Taz 5, Lulzbot Mini, MakerGear M2, 3x Rostock Max, Sharebot Kiwi, Ultimaker 2, and UP Mini, UP Plus 2 and UP Box or $2,000 worth of 3D Hubs 3D print credit.  Additionally, all contest entrants will receive $10 off their order from 3D Hubs!

Entries will be judged based on clarity, ingenuity, creativity, quality of presentation, and execution of the Instructable. The 14 winners will be randomly assigned a prize. Start thinking (and creating) in three dimensions!

Don't have a 3D printer? With the contest, we are excited to announce the launch of the Instructables “3D Print” button for STL files. It connects you with a 3D Printer in your neighborhood, making it fast and affordable to take your project from digital to physical.
