Design Brief

Attention please, this is a call to all future, past and present mechanical engineers!

Tinkercad and MyMiniFactory are back with one of their famous contests.

This time we are looking for talented designers to create wacky mechanisms and interesting components for moving machines. It’s time to awake the engineer in yourself and unleash all your creative power, use all the Tinkercad functionalities to design the funniest geared machine ever conceived by humankind!

Make sure you design the object on Tinkercad’s easy-to-use software and upload it directly to MyMiniFactory using the built-in “Upload to MyMiniFactory button”. Don’t forget to tag your creation in the description or title using #TinkerMechanical.

Once your design has been uploaded and approved on MyMiniFactory, make sure you share it on Twitter with the hashtag #Tinkermechanical @MyMiniFactory @Tinkercad @ivi_3d.

Greg Zumwalt, the brain behind some of the most beautiful and intriguing mechanical designs on MyMiniFactory, will be the judge for this competition. His unrivalled mastery in conceiving complex, fun and curious designs is an endless source of inspiration for many 3D designers. His wisdom will be used to select and award the best design in terms of functionality, quality of print and an overall element of surprise. Have a look at his profile and his youtube channel, you will surely find inspiration for your next creations!

    Q: A jumping robotic grasshopper, maybe?

    Don’t forget: the more the better. Any design is welcome, sketch your idea and create the mechanism that will surprise the community.


IVI 3D, The Multi-Tool 3D printer


IVI: The Closed-Loop 3D Printer

IVI is a closed-loop 3D Printer that allows users to easily achieve high-resolution 3D printing, laser engraving, and CNC carving. This easy-to-use desktop 3d printer with triple functionality, super-high resolution, and super success rate is ideal for beginners, hobbyists, engineers, and designers.

Precision & Reliability

Compared with other desktop 3d printers on the market, IVI achieves a staggering 15-micron/0.015 mm XYZ accuracy. Even when the print head is traveling at 300 mm/s, its repeatability is kept within 10 microns/0.01 mm. Along with phenomenal accuracy, IVI utilizes a closed-loop control system. This exclusive technology ensures unparalleled repeatability and reliability. Even projects requiring extended print times are completed flawlessly.

Top Tips

So you want to win a design competition?
Here are some top tips to help you climb up the leader board:

1. Think about your design(s) in relation to the brief and how best you might best optimise it for 3D printing.

2. Make sure you download all designer resources so as to ensure you design for the right size components if you are not printing your own submission.

3. Make sure to upload your design from within Tinkercad. Look at our blog post here for more information on how to do this.

4. Once your design is approved, post it on twitter with #TinkerMechanical @MyMiniFactory @tinkercad @ivi_3d

  • Read and understand the design brief.
  • Thinkabout how you can best deliver a solution.
  • Use the tips and resources provided
  • Explain the concept behind your design.
  • Presentprint, and photograph your design with care.
