Starting Jewelry Design Journey

Hello Everyone,

I am a newbie and have a question - I am about to create my first ring design project that I plan on uploading to Shapeways.
I will be using Rhino to create 2 rings - male/female versions, cast in silver.

There are mesh setting in Rhino that I need to address:
Properties > Mesh > Custom:
Maximum distance, edge to surface: 0.01
Maximum initial grid quads: 16
Refine Mesh: Checked
Simple Planes: Checked

Export STL for upload.

Are there any other items I should be aware of when setting up my file and exporting for production when it comes to using Rhino?

Thanks for your advice!

If Rhino has a way to be sure the surface is manifold, that helps to avoid geography that can not be printed.

Thanks Lawrence, appreciate the tip - to be clear can this also mean that the solid must be a 'closed polysurface'?

Hi Andreu,
Not sure about the Rhino terminology.
I'm using Blender with the 3D printing add-on. Every software package seems to like to use slightly different terminology. But the term seems reasonable. Maybe a Rhino user will chime in...
Best Wishes,
Lawrence
