During this project, students will further develop their knowledge of the use of TinkerCAD. Students will learn how to create the most effective wheels (Size, depth, weight) for their cars to ensure the fastest time when cars are used in the Race.

Students will be able to:

• Understand the proportion of the wheels needed.
• Consider shape/size
• Understand Tinkercad
• Learn 3D printing techniques
• Create and print in 3D STL models of wheels needed for their cars
• Test various sized wheels to find most effective

Students to complete the car models.

Have examples of different wheels – various number of spokes, different sized wheels etc.

Students will need to create own accounts on Tinkercad and carry out the tutorials

Ensure all computers have Flash Forge finder installed

Ensure all students know their log in details for their school accounts

Book computer room and use of printer(s)

Re-cap the making of the car body and how the wheels will attach to the car using a dowel.

Discussion of tools within Tinkercad and how to perform basic actions.

Discuss different types of wheels and structurally which would best on car model.

Discuss size or car model and size of wheels in relation to scale/proportion.

Explain how to save the files and how to export to the suitable format (STL).

Explain the basics about Flash Forge Finder.

Explain how to prepare the 3D printer for launching jobs.

Step 1: Students to measure their cars and using paper, ruler, pencil and compass work out what they consider to be the correct size wheel for their car.

Step 2: Using google students to research different types of wheels and which type would be most effective for their car.

Step 3: Complete hand drawing of wheel – adding dimensions after discussion with peers.

Step 4: Draw/Create/Adapt wheels using Tinkercad – export to Flash Forge Finder and scale to ensure they fit to original drawing. Students will need to consider size/scale/proportion of wheels to ensure they fit the car – curriculum link to Maths and Engineering.

Step 5: Printing – each student to print the appropriate number of wheels.

Step 6: Students to attach wheels to cars.

Step 7: Test the cars – decide which wheel worked best for their car.

Step 8: If needed re-draw wheels, print and re-peat testing of cars.
