Minecraft torus generator

The major radius sets the ring, the minor one the tube thickness: a block donut for a space station, a round portal, a ring corridor or a giant pastry. 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

• Ring 12/3
• Fat donut 8/5
• Big ring 24/4

FAQ

Which radii give a clean donut?

The major radius should be clearly larger than the minor one — 12 and 3, say — so a hole stays in the middle. With close radii the hole closes and you get a squashed ball.

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.
