With this Instructable, we will learn how to create Sacred Geometry designs in Tinkercad, 3D print them and then assemble the designs into earrings.

Tinkercad is a free online site with creation tools for 3D projects. Give it a try, it has all the tools you need for basic projects and beyond.

Supplies

While a 3D printer is needed in this project, you can just mess around in Tinkercad to further your design experience.

A Computer - this is the best way to access Tinkercad
Wi-Fi
3D Printer (duh)
Fancy Filament (not required - average will work) I'm using a tri-color filament for this Instructable
Earring Findings - Jumprings & Earring hooks - Surgical Steel is best
2 Jewelry Needlenose Pliers

Step 1: Designing With Tinkercad

Open Tinkercad.com and register. It's pretty easy.

Press + Create > 3D Design
Head right and drag some Basic Shapes to your artboard > Play around

Check out my video to match up with this tutorial.

Select a solid cylinder and size it to 20mm wide and 2mm tall.
Grab a hole cylinder and size it to 18mm wide and 3mm tall.
Now select both objects and click the align tool (L).
Hit both center dots to center both of your objects.
Once they are centered, group them (ctrl G). This makes your ring shape.
Copy your ring (ctrl C) and paste it back down (ctrl V).
Place both ring end to end overlapping and then center them with the align tool - Left Middle Button (L).
Group (ctrl G) both rings and copy and paste them.
Select your second set of rings and rotate them 90 degrees, using the rotate arrows (click+shift+ctrl then rotate)
Select both sets of rings and align them again
Group > Copy > Paste > Align > Rotate 45 degrees > Group

The Align tool is just out of view of the camera, but is shown in the photo above. Select your items, press the Align tool and Align away.

Step 2: Jewelry Design Ideas

Using this process for different shapes and patterns can lead to a bunch of cool designs. I put a few more together in a matter of minutes and added the files to this step.

Step 3: Attaching the Earring Findings

This is the easiest part of the process and takes just a few seconds.

Grab the Jumpring with the Pliers
Place the Earring Hook and Earring in the Jumpring
Using both pairs of Pliers, twist the Jumpring until it is closed (see example)

These designs can also be enlarged to create necklaces and other types of adornment. Let me know if you had success (or not) creating your own jewelry.

It turns out that you now have a quick and easy jewelry making machine.
