The second-place winner will receive two spools of MakerBot PLA filament and have their design Featured on Thingiverse.

Honorable Mention

One or more Honorable Mention winners will have their designs featured in a Collection of Honorable Mention Designs on Thingiverse.

How to Enter

  • Design something! You can participate in this Challenge whether you're a 3D-modeling expert or an absolute beginner. In fact, we especially encourage entries from people that are beginners! See the 3D Design Tips below for information about how you can get started with a few free, easy 3D-design programs.
  • Post your design to Thingiverse. You can modify your design anytime up until the August 15 deadline. See the Challenge Entry Tips for ideas on making your entry as effective as possible.
  • Include the challenge tag. To be considered for this Challenge, your Thing must include the tag #BuildACastle.
  • Be a mathematician! Tell us about the mathematics you used, and show everyone the beauty of the numbers, patterns, or geometric figures you incorporated into your design. Consider including design instructions, math facts, and photos of your molds together with the sand creations you made with them, whether at the beach or at home..
  • Get your school involved. In addition to receiving a printer of their own, challenge winners will choose one of ten MakerBot-selected schools to receive a printer, as well. Encourage your school to post to the Our School Needs a 3D Printer! Thingiverse Group to be in the running.

    Challenge Entry Tips: Increase your chances of winning!

  • Design iteratively. Use all of the time available to you. Don’t be afraid to upload new and different versions of your work.
  • Tell the story of your design. Take time to write a good Description and Instructions for your model on Thingiverse. How did you design your model? What did you have to redesign along the way? What does your model do, and why is it cool? What settings do you recommend for 3D printing your model?
  • Make it 3D-printable. While owning a 3D printer is not a requirement for entry, printing and documenting printability will go a long way toward winning. You might consider getting your design 3D printed locally at a service such as 3DHubs so you can test it and take photos.
  • Take good photos to show off your work. Photograph your design from every angle and upload all of your best, most informative pics.
  • Consider a video. Sometimes a video speaks louder than a photo, especially if your design moves or interacts with things. You can upload a video clip to the Thing page for your model by posting the model to YouTube and then including the link to that video in the Description. The video will then automatically be included in the Gallery for your Thing.
  • 3D Design Tips: How to get started...

  • Design on an iPad starting from 2-dimensional drawings with MakerBot Printshop. If you can draw a picture, then you can make a 3D design with the ShapeMaker feature in the MakerBot Printshop iPad app. Just draw, take a photo of your drawing, and extrude to make a 3D model. Then use MakerBot Desktop to export your model as an .stl file.
  • Design online with Tinkercad. If you're just getting started then Tinkercad is a great place to start, and it's especially friendly for kids. Tinkercad is a free online in-browser 3D design program with a drag-and-drop interface and Lessons to help you learn the ropes.
  • Design by scanning with 123D Catch. Some 3D models start with scans of actual real-life objects. With 123D Catch you can use your cellphone or iPad to take pictures around an object that are then stitched together into a 3D model. After scanning you'll have to analyze your model, repair scan defects, and possibly remix or add things with a program like MeshMixer.
  • Design in code with OpenSCAD. By writing just a few lines of simple code you can make 3D models with the free 3D modeling language OpenSCAD. OpenSCAD is extremely accessible, if you've never coded before. There are lots of tutorials on YouTube that can help you get started. It's easier than you think, and will allow you to make customizable designs that you can include in the MakerBot Customizer!
  • Or use any program you like! To enter this Challenge you can design with any program that can export an .stl file. Some of the many other free design programs that you might like to try are MeshMixer, 123D Design, Sculptris, Sketchup, Morphi for iPad, or Blender.
