Binding occurred between the cylindrical spinner and the cylindrical base. The spinner could fit into the base but there was light friction and no room to wobble. A revision made the edges rounded so any rotation from the pivot point would not bring an edge closer to the edge of the base. The intersection() command was used with a sphere centered on the pivot point.

Another update to the spinner was a keyed bottom. The negative space shape of the hole in the bottom was a simple cone but it was narrowed so that a similarly keyed post will not allow wobbling unless the spinner and base are aligned.

Revisions to the base changed the post to a shape which mates with the keyed hole in the bottom of the spinner. Hopefully the spinner will freely rotate, like a typical compass, but when the spinner and base are both pointed north or south the spinner will be able to wobble. This wobbling would allow the spinner to create impacts felt by a user.

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
