Tutorial: Truncated Icosahedron (Zen Magnets)

Tutorial: How to Make a Truncated Icosahedron (Soccer Ball Shape) with Zen Magnets

Materials Needed:

• Zen Magnets
• Cardstock paper
• 12 large pentagonal subunits
• 30 small subunits

Step 1: Prepare the Support Ring

1. Cut a piece of cardstock paper into a ring that is 1 inch thick and approximately 4 inches in diameter.
2. Curl the cardstock into a ring shape to provide support for the structure.

Step 2: Create Small Subunits

1. Start with 12 Zen Magnets to create a small subunit.
2. Arrange the magnets in a square of 4 magnets.
3. Continue adding magnets around the square until you form a small pentagonal shape.
4. Pinch the magnets together to secure the shape.
5. Repeat this process to create a total of 30 small subunits.

Step 3: Make Large Subunits

1. Stack two rings of 20 magnets each to create the base of a large subunit.
2. Add five additional magnets between the two rings to secure them.
3. Stack two rings of 40 magnets each on top of the previous rings.
4. Place five additional magnets between the top rings, ensuring they are evenly spaced.
5. Separate two magnets on each side of the subunit to create a stable structure.
6. Repeat this process to create a total of 12 large pentagonal subunits.

Step 4: Assemble the Truncated Icosahedron

1. Attach the small subunits to the ends of the large subunits by connecting the magnets.
2. Create different types of subunits with varying numbers of small subunits attached: five, four, three, two, one, and none.
3. Start assembling the structure by placing the subunit with five small subunits attached at the bottom.
4. Attach the subunit with four small subunits to the structure.
5. Use three subunits with three small subunits attached in a row to add stability.
6. Add the subunit with two small subunits to support the structure.
7. Place the paper ring inside the structure to provide additional support.
8. Continue adding subunits with decreasing numbers of small subunits until you complete the truncated icosahedron shape.
9. Adjust any loose magnets to ensure a stable and symmetrical structure.

Step 5: Finalize the Truncated Icosahedron

1. Check the edges and adjust any magnets that may be sticking out.
2. Ensure all subunits are securely attached to create a cohesive truncated icosahedron shape.
3. Admire your creation, which resembles a soccer ball shape with a unique geometric design.

Conclusion: By following these steps, you can create a beautiful truncated icosahedron structure using Zen Magnets. Enjoy the process of assembling this intricate geometric shape and appreciate the craftsmanship involved in making a soccer ball-like design.
