This challenge is open to projects that celebrate retro tech!

You can restore a piece of old tech, make new tech look retro with a custom 3D printed case, or create a DIY version of your favorite arcade machine from the 80s - as long as your project is retro in age or looks and involves technology, it's eligible.

Show us how to design a retro tech project using Tinkercad and you could win our $200 Tinkercad Judges' Prize!

(Unsure what we mean by "retro"? Check out our Best of Instructables: Retro Tech Projects collection to see a variety of projects that fit the theme.)

The Retro Tech Challenge is closed.
