The place for the compass spinner to rest was simply left as a hole which may be useful later but the first model will need divots. The first logical shape was a hollow cone. The cone will guide a spinner directly to the center which will ensure accurate positioning. The worry is that the steep, sharp edges of the cone will introduce a lot of friction. Ideally the spinner would be a sharp point meeting a blunt surface since the sharp point will not have a lot of friction, similar to an overturned tea cup balanced on a knitting needle.

The pictures taken for the blog were rendered directly from OpenSCAD rather than using screenshots. This provided a cleaner picture without the unnecessary code window and feedback window.

To do:
  • Design hemispherical spinner rest
  • Design spinner for spheroid compass
  • Design spinner mount for tubular compass
  • Install larger bearing 
  • Cut/bend hanging bracket for spinner
  • Buy spongy material for spinner to land on
  • Test + Evaluate hanging tubular compass
  • Redesign, Rebuild, + Repeat

The rest of the posts for this project have been arranged by date.
