Modular spiral staircases in different sizes

Slab

Spiral stairs with different diameters and rotations

Small – 4×4

Medium – 5×5 + extra 6×6

Large – 8×8

Giant – 12×12

Sections are modular if you use 90° or 360°. Stacking the others will get weird in some cases.

How to:

1. Do not delete orange “anchors” until the section is properly placed unless you need to.
2. Turn on grid (press G).
3. Place first section.
4. Increase building height until only 3 stairs/fences are visible through the grid.
5. Line up next section and place it.
6. Repeat until target height.
7. Delete orange “anchors”.

Shoutout to @lebion_ who showed me the method with his stairs post on talesbazaar.
