AI Tabletop Terrain Generator: Printable Scatter Terrain at 28/32 mm

Pick a piece such as a ruined wall, a rocky outcrop or a stack of crates, or describe your own, and choose your game scale. The page writes a prompt that asks for one chunky, solid piece on a flat base with 2 mm walls, and tells you how tall to print it. Generate the STL in Text to STL, scale it, and print scenery for tabletop RPGs and wargames.

1. Pick or describe a piece

One piece at a time. Pick a preset to fill the box, then change any words you like.

Use your own idea, not a game, film, book or brand name.86/90

2. Pick your game scale

The scale is how tall a person is. 28 and 32 mm suit most tabletop RPGs and skirmish games; 15 and 6 mm suit big-battle wargames.

Target heights are common guidelines, not a standard: a person is about as tall as the scale name, and each piece is sized from the real object next to an adult. Makers measure scale differently (feet to eyes or to the top of the head), by up to about 30%, so match your own miniatures. Heights include the base.

Make a few, not one

Generate the same prompt two or three times. Small differences between rocks, crates or trees make a table look natural.

How to make 3D printable terrain with AI

  1. 1

    Pick a piece and a scale

    Choose one of the 12 scatter pieces or describe your own, then pick 28 mm, 32 mm (heroic), 15 mm or 6 mm. The page writes the prompt and shows the target height.

  2. 2

    Generate the STL

    Press Open in Text to STL: the prompt goes into the Prompt box (or copy it and paste it in). Generate, then download the STL when it is done.

  3. 3

    Scale and check it

    AI models have no fixed size. Scale the STL to the target height in Scale STL, then check thin walls before you slice.

  4. 4

    Print and paint

    Print it flat on its base, usually without supports. Make a few variations of the same piece so your table does not look copy-pasted.

What to expect from AI terrain

  • Each generation is different. You will often want two or three tries to get the piece you pictured.
  • Thin parts are the weak spot: tree branches, fence rails and flames can come out thinner than 2 mm. Check the STL and regenerate if needed.
  • AI models have no fixed size. Scale every STL to the target height for your scale before slicing.
  • It makes one piece at a time, not a modular tile system: pieces will not snap or clip together.
  • At 6 mm and 15 mm, fine details shrink to fractions of a millimetre and may not print. Keep those prompts simple.

AI tabletop terrain generator FAQ

You pick a scatter piece or describe your own and choose your game scale. The page writes a prompt that asks for one solid, chunky piece on a flat base with 2 mm walls, and shows how tall to print it. You paste the prompt into Text to STL, which builds a 3D model you download as an STL.
Each piece is one Text to STL generation. The exact credits are shown next to the prompt. The height table and the prompt writer on this page are free.
A figure scale names the height of a person, so at 28 mm a person is about 28 mm tall and at 32 mm (heroic) about 32 mm. A waist-to-chest high wall is roughly a person tall or a bit less, a door or archway about 1.7 times, and a tree 2-3 times. The table on this page lists all 12 pieces at 28, 32, 15 and 6 mm. These are common guidelines; makers measure scale differently, by up to about 30%.
Usually yes. Most scatter terrain such as rocks, crates, barrels and trees works for both, because real objects vary in size anyway. Doors, archways and fences are where it shows, so scale those to the 32 mm height in the table (about 14% taller).
The prompt asks for one solid piece on a flat base with 2 mm walls and no thin parts, which prints well on most FDM and resin printers. AI output still varies, so check the STL in the wall thickness checker before slicing and regenerate if a branch or post comes out too thin.
Most scatter pieces are under 80 mm even at 32 mm scale. For a big ruin or tree, cut the STL into parts that fit your bed with the STL splitter, then glue them after printing.
Not by name. We can't make other people's designs, so game, film, book and brand names are not accepted. Describe the look instead, for example "gothic ruined chapel wall" or "sci-fi cargo container". The pieces here are generic and work for any tabletop RPG or wargame.
No. This page makes single scatter terrain pieces: one wall, one rock, one tree at a time. That keeps each print small and easy to arrange on the table. For flat battle maps or full scenes, use a dedicated tool.
