Role

Individual project

Responsibilities

Design, prototype, and print the final product

Skills

3D printing (FDM), CAD

Challenge

Experiment with print-in-place joints to create assemblies unique to additive manufacturing.

Time Turner

Design Considerations

Action

  • Designed a Harry Potter inspired time turner with three rotating components. The entire assembly was one single print using five print-in-place joints.
  • Tested the tolerance of each joint through prototyping and practiced robust modeling techniques for quick iteration.

Prototype 3

Prototype 4

Prototype 5

Result

  • Learned how to isolate components in CAD in order to only prototype critical parts and avoid printing the entire assembly every time.
  • From experimenting with the tolerances, I also learned that the dimensions of the joint can change the required offset distance.
