Both printed spinners were leveled with a piece of 150grit abrasive paper held by a standard clipboard. A clipboard was used to ensure the paper would be stationary and flat. Flat faces on the pieces would help them to fit together flush. Two pictures were taken, one was taken before the pieces were sanded and a second picture was taken parallel to the tops to show how they had been flattened.

The older model was also sanded. A neoprene grommet was inserted in the new model and a neoprene washer was inserted in the old model. There shouldn't be any issue with performance between the washer and the grommet but any differences should become apparent. Each of the halves were taped together with ordinary masking tape.

Narrated video was taken to show the differences between the two newest spinners and one of the old styles which was printed as a single piece. It was apparent how well the old spinner would spin compared to the new models but the plastic-on-metal collisions were unacceptable. It should be possible to redesign the model so it can be printed to optimize for spinning while still using the grommets or washers to reduce unwanted collisions.

To do:
  • Remodel into a 3 piece design
    • Post cone receiver
    • Grommet adapter, side 1
    • Grommet adapter, side 2
  • Make handheld haptic compass
  • Make compass work from pocket or necklace
  • Miniaturize
