Wk3: Oyster Ring Holder

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.

Supplies

3D Printer, filament

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.

    What a lovely and well executed idea! I like the divot and the way the final form really evokes the oyster shape that was the original inspiration. I think it was also interesting to see how used testing and experimentation in your process

    Thanks Sonia. I was surprised by how effective it was to start with a tracing. The concept of the oyster was able to "speak" clearly once that original curve was traced.

    I like the shape you went with! Did you get a chance to print the whole thing?

    Thanks! I just added images of the printed ring holder.
