Key facts
| Diameter | 21 |
| Blocks | 340 |
| Depth | 9 |
| Layers | 9 |
| Height | 9 |
Materials needed
To build this Ellipsoid you will need:
| 340 blocks | 340 |
| 6 stacks of 64 | 6 |
| about 2 minutes | 2 |
All three axes are different - the widest ring is horizontal, while the height and depth axes shape the rest.
How to build it
- Lay the widest ring on the long horizontal axis first.
- Build the depth-axis ring at right angles through the center.
- Stack layers toward the top and bottom, shrinking the ring each time.
- Keep the three axes symmetric - width, height and depth.
- Smooth the surface with slabs where the curve is steepest.
