I was intrigued by John Edmark's Helicone when I saw it on a tweet by Clifford A. Pickover.
I wanted to figure out how it worked and came up with the thing you see here. It is not as nice as the original but it seems to operate in the same fashion.
How to print:
- PLA, 0.3mm layers, 20% infill, no supports.
What to print:
- 1 firstSegment,
- 17 segment,
- 1 shaftNHandle,
- 1 endCap.
How to assemble:
- Set the first segment on the shaft so that it locks in place (the first segment doesn't move),
- Add the other 17 segments,
- Put the end cap.
