I needed some nice looking rings for my Secret Wedding Box project so I created some. Some settings are customizable.

Version: 1.0.0

Show / Customize / Instant Edit

Customize: Just edit the parameters(bottom left), click "update" then "Generate STL" and "Download STL". BOOM ready to print.

Example

The Example you can download directly at Thingiverse is a high resolution version with default parameters.
