A base was modeled to provide different keyed posts for testing the keyed spinner. All the keyed posts modeled previously were so small that they would not create significant differences in the wobbling no matter which direction the compass pointed. A hole in the center was also printed to test an ordinary #4 brass screw. Each test post was spaced to provide enough room for unimpeded movement.

Base printed to test different pivot dimensions

Video was taken with narration to show the change in movement while the compass spinner pointed in different directions.

Narrated video demonstration

To do:
  • Optional:
    • Add compass rose to spinner
    • Add holes to reduce plastic
  • Add “keyed” features to only allow slop when facing north
  • Make handheld haptic compass
  • Make compass work from pocket or necklace
  • Miniaturize
