2015 Winter Wonderland 3D Print Challenge

UPDATE 12.17.15

All submissions are being shared here in this album. I have shared screenshots of prints as I was not able to take all of the support and rafts off. I took pictures of prints with supports still attached to keep them from breaking in delivery. When students submit me pictures after the removal, painting, and modifications I will share.

I also shared this video with them to get them started with painting, removal of support, etc.

If I left your print out of the collection please let me know so I can add it to the album. So many great prints. They were so much better than the collection last year.


Call For Entries: Winter Wonderland 3D Print Challenge


November 3 – December 18, 2015

**If you would like us to print and mail back in time for the holidays we will need your designs by December 5th.**

Invitation to Submit Winter Wonderland 3D Print Challenge

This year we are hosting two categories for the Winter Wonderland 3D Print Challenge

Category 1: 3D Ornament Festival of Trees

Category 2: Winter Wonderland Scene

For more information contact Aaron Maurer at aarmau@gmail.com

Delivery/Shipping for Accepted Works

Last year we were able to print the ornaments for classrooms free of charge. This year we will be able to help with the printing. However, due to material costs and shipping we are going to have to charge a small fee. If you would like us to print your materials, then we will be asking you to cover the shipping costs and a small fee to help with printing costs and maintenance of machines. We are not making any money off this challenge, but need to ensure that we can provide for everyone.

Ornament Restrictions – Due to filament supply and sticking to ornament sizes please adhere to a max size of  3”x 3” x 3″ for ornaments. As long as your ornament reflects winter and holidays you are golden. Let your imagination run wild. Can you infuse lights? Can you make it move? Sure! It is up to you!

Winter Wonderland Scene – Due to time constraints and to see how this category turns out please adhere to a max size of  6 x 6 x 6. As long as your ornament reflects winter and holidays you are golden. Let your imagination run wild. Can you infuse lights? Can you make it move? Can you connect to littleBits, Raspberry Pi, Arduino, Scratch? YES! YES! YES!

Submission Guidelines – In order to submit an ornament, please send me an email that includes

  • STL file of the ornament or link to online design
  • Name of school
  • Address of school
  • Anything else you need to share about your ornament

You can use any program or app that you wish as long as you can provide a .STL file. If you are brand new to 3D modeling, don’t worry. Use Tinkercad and in no time you will be up and running. This is what all my students will be using.

When you submit your design I will do three things.

  1. Print a copy to add to my Coffeechug Cafe Tree(see how lonely my poor tree looks! It needs your help to get into the holiday spirit.)

  1. Print a second copy to send to you if you agree to cover the costs for shipping.
  2. I will share your files, documentation, and name for others to use your ideas and spread the power of crowdsourcing and sharing ideas.

3D Print Submission

1. Please share with Coffeechug so we can show off your work. Email to aarmau@gmail.com

I will need your .stl file so I can print it if needed, or an image of your print if you print it yourself. Better yet will be photos and videos of the work in progress.

2. Enter your design to Polar 3D so you can be entered to win some prizes.

Now some of you have makerspaces and 3D printers and do not need me to print for you. I want you to share your designs. You don’t need me to print your ornaments. Please reach out to me with a link to your site so we can create a Festival of Trees! I will add your page/website to this page for others to check out. The more we share the more everyone learns. Please share to the Facebook group.

Here are the ornaments from last year. We look forward to another great year of creating!
Join us on Facebook where we have a group page to share ideas, ask questions, submit pictures, etc.

Use the hashtag #3dwinter

Let us create some amazing designs and really up the festive spirit of the holidays.

UPDATE 11.6.15

Polar 3D has reached to help support this project. Polar 3D has announced that they are going to help raise the stakes a little bit by providing the winning student or creator from each school one dozen prints of his or her ornament.

The Polar 3D Headquarters now has on site printers to help makers print who don’t have printers. They have created what they call the Polar Farm which is a large amount printers to help make this happen.


Check out the page to submit your files here at our Polar 3D Challenge page so you be entered to win!

So, what are you waiting for? Jump in the action. Who will be the first to submit a design? Who will have the winning design of your school?
