This lesson is an introduction to Tinkercad, 3D printing, and building classroom community through the creation of a personalized classroom rubik’s cube.
Students will be working in teams to generate a 9 letter word or word with a combination of symbols to represent the chosen topic.
Students will be working collaboratively in Tinkercad using a pre-made base to add the letters of the chosen word.
Building classroom community and social and emotional learning through which learners acquire and effectively apply the knowledge, attitudes, and skills necessary to understand and manage emotions, set and achieve positive goals, feel and show empathy for others, establish and maintain positive relationships, and make responsible decisions.
This lesson helps reinforce four of seven strategies for building positive classrooms:
Make Learning Relevant
Create a Classroom Code of Conduct
Teach Positive Actions
Reinforce Positive Behaviors
Lesson - Part 1: Brainstorm and Share Out
Duration: Approximately 30 Minutes
Share example of final product (image) so that students understand what they are designing to represent their classroom or selected topic.
Divide students into six random groups. As a team, students will have 10-15 minutes to generate as many nine letter words or a combination with symbols that represent the topic on the chart paper or collaborative document.
The desire is to not repeat words which is why the group share out is important. Highlight which words are being repeated and then after each group has shared out, have each group select a word that they are going to create.
Lesson - Part 2: Importing an Image into Tinkercad
Duration: Approximately 10-15 Minutes
Tinkercad allows the import of either an .svg or .stl file.
An .svg file can be a converted .jpg or .png file. I use the following .svg converter - http://picsvg.com/
An .stl file is any file that has been created for 3D printing. This import ability allows the designer to import any 3D design and rework it or build upon it. In this project, you can use the .stl to build the final pieces.
Lesson - Part 3: Creating with Tinkercad
Duration: Varies by level
This is the step where differentiation should occur based on your knowledge of your students.
For younger students or students who have never used Tinkercad:
Using the attached generic .stl file, students can import the basic foundation of the project into Tinkercad and drag and drop the letters of the word on the tiles. Tinkercad is not a collaborative application but for this part, each student or pair of students could do the word to be introduced to how Tinkercad works.
For older students or students who have used Tinkercad:
Students can measure the squares of the Rubik’s cube and design from the beginning. Tinkercad is not a collaborative application but for this part, each student or pair of students could do the word to be introduced to how Tinkercad works.
For an even more advanced level of using Tinkercad:
Students can use one image instead of individual letters that cover a full 9 block section. (See attached images provided by Drew Lentz)
Lesson - Part 4: Exporting and Printing the Design
Duration: 45 minutes per 9 piece side.
Students will need to export the design for 3D printing from Tinkercad as an .stl file and share it with the teacher for final printing.
Printing will take approximately 45 minutes per 9 letter section.
Resolution: 0.2 mm
Lesson - Part 5: Adding the Design to the Rubik's Cube
Dueration: Approximately 15 minutes to apply and an hour to dry
Use Gorilla Glue to apply each piece to the Rubik’s Cube by moistening the two sides that will be adhering together. Use very little glue as it expands. It will take about an hour per side for the glue to dry and adhere permanently. Do not speed up this process as it will result in pieces moving and sliding.
Chart Paper and markers or Collaborative Google Doc for each group
Computers for Tinkercad
Standard Rubik’s cube (six sides with 9 squares on each side)
6 filament colors (preference of red, blue, green, yellow, orange, and white)

- 3D Design
The assessment should occur before sending the word to be printed.
