Introduction: Wk3: Oyster Ring Holder
This project is a collaboration between my partner Nicole and I. We were brainstorming on possible projects when Nicole suggested a ring holder. This subject supported our goal of collaborating on something that is both beautiful and functional.
After some introductory sketching helped us rough out the design concept, I imported an image of an oyster shell into Rhino for tracing. I used the bezier tool to construct a closed curve based on the image of the oyster.

Step 1: Extrude Curve to Point
With the curve, I used ExtrudeCrvToPoint to turn the curve into a polysurface roughly shaped like a pointy shell.
Step 2: Extrude Surface
I then used ExtrudeSrf to transform the surface into solid geometry suitable for printing.
Step 3: Transform
At this point, I scaled the shell shape up to match my desired dimensions.
Step 4: Conical Primitives
I used the cone primitive in Rhino to construct the base and the ring holder itself.
Step 5: Extrude Curve (again)
For the bed of the shell, I used the original traced curve and executed a simple extrude command to transform the curve into a thin platform that rests on the main shell mesh.
Step 6: Test Print Story
After going through the design flow once, I decided to do a test print of the cropped ring holder to test it with a real ring.
I'm glad that this was possible. This test print revealed that our ring holder shaft was far too large. Going back, I resized the ring holder shaft and added a small divot to make it easy to store a pearl up there.
Step 7: Images From Cura
Video and image from the slicing process.
Step 8: Resulting Piece
The print came out very well.
We are planning to sand out some of the roughness and paint it.
