Exciting engineering challenges with great prizes

Show off your skills and solve real design problems

GrabCAD Shop Challenge


Welcome to the first GrabCAD Shop Challenge. With the release of GrabCAD Shop, we wanted to see what you could create. With this challenge, we would like you to create a functional tool that we can 3D print and it be requested on GrabCAD Shop!

We are looking for the Community to create something unique to be 3D printed. How far can your own creativity take you to create something great?

Now you are asking yourself what should I create? We can help by putting you on the right path. We would like you to create something that can be used in the real world. May it be a camera mount, a door stopper, a stronger screwdriver, or a jig and fixture that no one has created before. We want you to come up with something and give us reasons for why this is practical and useful in the real world and how 3D printing can help speed up this process.

All finalists will be invited to check out GrabCAD Shop. You’ll be able to use Shop and showcase its features. You will even get the chance to send your entry as a print job using GrabCAD Shop, when we’ll then 3D print it for you.

    2. A Document explaining what problem you wanted to fix and how your part will fix that problem. Must go into detail on why your part is considered the best solution for this problem.

    Just a quick question for this challenge- can the submission be decorative, with a functional purpose? For example if I were to design a unique, decorative desk organizer, with the purpose of clearing clutter on my desk and presenting an aesthetic and minimalist appearance, would that be permitted? Or is the challenge more geared towards 'tools' and similar objects? Thank you, and I look forward to competing!
