There are things in the universe that are out of our physical reach; they are either too small, too large, too far away, or hidden entirely from view. For the Untouchable Challenge, take inspiration from something that's normally untouchable, and make something touchable. All projects inspired by things-untouchable will be eligible.

Two grand prizes are provided by Ultimaker: one for the best 3D printing-related project, and one for the best non-3D printed project. Create something amazing and win!

For some ideas check out this collection of touchable objects inspired by untouchable things. And be sure to take our 3D Printing Class and 3D Scanning Class to brush up your 3D modeling skills. Be sure to give Autodesk Fusion a try; it is free forever for hobbyists and startups & students and educators.

The Untouchable Challenge is closed.

How It Works

Write an Instructable

Create a new Instructable that fits the guidelines outlined in the contest description above. To be eligible, Instructables must be published between May 7, 2017 and Jun 19, 2017 (11:59pm PT).


Upon publishing your Instructable you'll see checkboxes for open contests. Select Untouchable Challenge. If you have entries currently eligible for entry, it will also show up by clicking "Enter this Contest" on the right side of this page.


Entries are accepted by Instructables staff within one business day Monday - Friday. What matters is the submission time, not acceptance time.


A panel of judges made up of Instructables staff and respected members of the community rate the finalists. The averages of the ratings determine the winners.


When the winners are decided they will be notified and announced here on the contest page.
