Introduction: Yin-Yang Necklace (3D Printed) Using TinkerCAD

Tinkercad Projects »

To start, I will be using the TinkerCAD 3D modeling program.

First, find a flat image of only ONE half of the Yin-Yang that you would like to use, for best results look up Yin-Yang PNG or Clipart.

Step 1: Step 1:Converting the Image Into an STL. File

Next, save the image to your computer and go to this site: https://convertio.co/. This will enable you to convert the image you saved into a 3D Model. Convert the file into an STL.

Step 2: Step 2: Adding the Shape.

Open TinkerCAD and import the STL. file using the "import" button. Sou should have something that looks like this.

Step 3: Step 3: Configuring the Shape.

Scroll through the shapes library until you find the "Ring" shape. You could use the "tube" or the "toroid" shape, but the ring shape makes things a lot easier and makes it look better without the extra hassle.

Step 4: Step 4: Getting the Shapes You Need.

Place the ring on the workspace and size it up so it's just barely bigger than the necklace half.

Step 5: Step 5: Getting Shapes (continued).

Next, get a "toroid" shape and stretch it so it's the same height as the ring.

Step 6: Step 6: Beginning the Process of Construction.

Take the ring and cut it about in half. I found it helps to put the necklace half in there, just make sure to remove it when you cut it.

Step 7: Step 7: Construction (continued).

Carefully line up the necklace half in the half-ring. Then group them together by selecting both of them (click and drag) and pressing CTRL + G.

Step 8: Step 8: Construction (continued).

Add the small toroid onto the necklace half.

Step 9: Step 9: Construction (continued).

Now, copy (CTRL + C) and paste (CTRL + V) your progress so far. Then, using the mirror/flip tool (in the top right, it looks like 2 triangles), mirror the project both vertically and horizontally. Then, turn one of the halves into a "hole" by selecting the gray stripes that come up in the color selection when you select the shape.

Step 10: Step 10: Construction (continued).

Carefully line up the two pieces against each other and group them together. This will ensure that the two pieces fit together perfectly when they are printed.
