A tube and cap were printed. The tube was taller than any previous version. The cap's node was larger  than any previous version by 0.25mm. The cap fit securely in the tube and remained in place without any outside pressures. The goal with this model was to get a step closer to a self-contained working prototype which could be placed next to the skin to simulate implantation in terms of effect.

 New tube on right for comparison with old tube height

Noticeable gap difference between old and new design
Screw can be inserted further than old model to allow for more adjustability

The spinner had trouble staying in contact with the screw tip so the screw was replaced by a bolt since since the tip of the bolt was a plane instead of a point. The spinner stuck stuck to the bolt well but didn't release as easily as desired. A larger steel bearing may be the easiest solution. This would add weight to the spinner and add distance between the bolt and magnet.

To do:
  • Resize components
  • Reprint
  • Install larger bearing 
  • Cut/bend hanging bracket for spinner
  • Add direction arrow to base
  • Buy spongy material for spinner to land on
  • Design bottom for compass to land on
  • Test + Evaluate hanging tubular compass
  • Redesign, Rebuild, + Repeat
