Key facts
| Diameter | 121 |
| Blocks | 18005 |
| Layers | 61 |
| Height | 61 |
Materials needed
To build this Dome you will need:
| 18005 blocks | 18005 |
| 282 stacks of 64 | 282 |
| about 76 minutes | 76 |
Layers shrink as you go up, so the ground ring uses the most blocks. A center pillar keeps every layer aligned.
How to build it
- Start with the full base circle on the ground, just like a flat circle.
- Stack each next layer with a smaller ring, keeping the same center.
- Follow the blueprint layer grid for the exact ring size of every layer.
- Use slabs or stairs to smooth the curve as it gets steeper.
- Close the top with the smallest ring and fill the center block.
Copy it as /setblock commands
Open the generator and hit Copy /setblock to get every block as a Minecraft command. Add your world coordinates and the whole Dome lines up exactly where you want it to be.
