Course Description

This course teaches jewelry designers how to model functional and manufacturable jewelry clasps using Rhino 3D, with an emphasis on accuracy, durability, and production-ready CAD practices.

You’ll learn how to build a range of commonly used clasp mechanisms, understand how clasp design affects wearability and strength, and prepare clasp models for casting and integration into complete jewelry designs.


Who This Course Is For

  • Jewelry designers who want to model functional clasps instead of relying on stock components

  • CAD users looking to improve mechanical accuracy in jewelry designs

  • Designers creating necklaces, bracelets, and chains for real-world production

  • Students and professionals refining practical jewelry CAD skills


What You’ll Learn

  • Students will learn how to model a variety of functional jewelry clasp types in Rhino 3D, including:

    • Spring clasps

    • Toggle clasps (two toggle clasp variations)

    • Lobster clasps

    • Barrel clasps (two barrel clasp variations)

    • Fold-over clasps

    • Magnetic clasps

    • Screw clasps

    • Pearl clasps

    • Box clasps

    • Twist-lock clasps

    • S-hook clasps

  • Understand functional considerations such as movement, tolerance, and durability

  • Build clasps suitable for casting and production workflows

  • Integrate clasp designs into complete jewelry CAD models

  • Apply consistent modeling logic for repeatable and reliable results

  • Work with provided sample clasp CAD files to support learning and practice



This course requires basic knowledge of Rhino 3D. Students should be comfortable with navigation, curves, solids, and basic modeling tools before starting.

A computer with Rhino 3D installed is required. A three-button mouse is recommended for efficient CAD modeling.

The Rhino trial version can be downloaded for free at https://www.rhino3d.com/download for 90 days. The Window system and three-button mouse is preferred.

FAQ

  • Do I need to have basic knowledge of Rhino before taking this course?

    Yes, a basic understanding of Rhino is required for this course, as it focuses specifically on Claps 3D modeling CAD design rather than basic Rhino 3D techniques. If you are new to jewelry CAD design, we recommend starting with our Jewelry CAD Masterclass, which covers the foundational skills you'll need.

  • Is the Rhino 3D software included with the course?

    No, the Rhino 3D software is not included. However, you can sign up for a 90-day free trial at www.Rhino3D.com.

  • Can I download the course to watch offline?

    Currently, we do not offer offline downloads through the platform. However, you can access the course anytime as long as you have an internet connection.

  • How long will I have access the course?

    This is a lifetime membership course, meaning you will have unlimited access to all the course materials, which are pre-recorded and available at your convenience. You can learn at your own pace.

  • Can I use Rhino 5 for the course?

    Yes, most of the commands taught in this course are compatible with Rhino 5 and newer versions. You should be able to follow along with Rhino 5 without any issues.

  • What if I need additional tutoring for my own Rhino CAD design?

    You can certainly request private tutoring for your specific design needs. Simply send us your design and the 3DM file, and we will provide you with a customized estimate and schedule. Tutoring sessions are available for an additional fee, tailored to your individual project.

  • Do you offer subtitles in languages other than English?

    At this time, we offer subtitles in English only. However, you can use the "Live Caption" feature in Chrome to generate subtitles in your preferred language. For more information on how to enable this feature, please visit: Chrome Live Caption Support.

Very straight-forward presentation! Some designs are really simple, but unless having followed this course I would have probably spent ages trying to figuer out how they are made. Thanks for the files, also!
