Key terms

OpenSCAD

A free program where you build 3D models with code instead of drawing. It runs on Windows, Mac and Linux.

STL

The model file format every 3D printing program understands.

Slicer

The program that cuts the model into layers and turns it into instructions for the printer. It usually comes with your printer.

Voxel

A tiny 3D cube. A pixel with depth.

The steps

1. 1

   Step 1

   Pick the emoji and get a clean image

   Take a clear capture of the pixel emoji or drawing on a plain background.

   The clearer the squares, the better Claude reads the grid.

   Tip: Use your own drawing or one you are allowed to print, not a company logo.

2. 2

   Step 2

   Ask Claude to read the grid

   Upload the image in a new Claude chat and ask it to write the grid as text, one line per row and one letter per colour.

   Check the text against the image before you go on. Every wrong square shows up in the model.

   PromptRead the grid

   Copy

   This is a pixel drawing. Write the grid as text: one line per row, one letter per colour (for example B for the body, H for the headphones, E for the eyes, and . for empty). Then list the colours you found.

3. 3

   Step 3

   Let Claude write the OpenSCAD code

   Ask it to turn the grid into OpenSCAD code: every coloured square becomes a cube, and every colour goes in its own part so you can print each colour separately.

   Give it a real size, like 6 cm tall, instead of "small".

   PromptOpenSCAD code

   Copy

   Turn this grid into OpenSCAD code. Every coloured square is a [2] mm cube, and the model is [6] mm deep. Make one module per colour and put a variable called part at the top of the file so I can choose which colour to export. The grid:
   [paste the grid here]

4. 4

   Step 4

   Run the code and export STL

   Open OpenSCAD, paste the code and press F6 to render the model.

   Then go to File, Export and choose Export as STL. Type a file name ending in .stl.

   Repeat for every colour by changing the part variable.

   Tip: If you get an error, paste the message to Claude as is and it fixes the code.

5. 5

   Step 5

   Open the files in your slicer

   Open the STL files in the slicer that came with your printer. Pick the filament and colour for each part.

   If your printer prints several colours, load the parts together. If it prints one colour, print each part alone and assemble them.

6. 6

   Step 6

   Print it or take the files to a shop

   Print the parts and glue them if needed.

   No printer? Take the STL files to any 3D printing shop and tell them the colours and the size.

Ready prompts to copy

The model came out [describe the problem, e.g. the legs are thin and break]. Edit the OpenSCAD code so [the fix, e.g. the legs are twice as wide] without changing the overall shape.

Add a rectangular base under the model, [2] mm thick and [4] mm wider on every side, as its own part.
