Minecraft cone generator

Base diameter, top diameter and height and the block cone is ready: a spire on a tower, a cap roof, a truncated cone for a chimney or a fir tree. Hollow or solid, in 3D at once, export to .litematic and .schem.

How it works

1. Set the dimensions with the sliders — the shape is recalculated instantly and shown in 3D.
2. Pick a block (some tools take two: main and secondary).
3. Turn on Layers to see the shape slice by slice — handy for building by hand.
4. Download .litematic for Litematica or .schem for WorldEdit.

Examples

• Spire 13→1
• Truncated 21→9
• Solid 9→1

FAQ

How do I make a sharp cone?

Set the top diameter to 1 and the height above the base: the taller the cone for the same base, the sharper the spire. A top wider than 1 gives a truncated cone.

How do I build this without mods?

Open the schematic in the viewer, turn on Layers and place blocks layer by layer on the grid. With Litematica or WorldEdit the schematic is pasted in one go.

Why does the shape look stepped?

Blocks are whole, so every curve turns into steps — the game does the same. An odd size gives a clean centre block, an even size gives two.

Is it free, no sign-up?

Yes. Everything is computed in the browser; the file is built locally and never uploaded.
