ArUco 4x4 1000 Dictionary

The complete ArUco 4x4 dictionary (IDs 0–999), optimized specifically for 3D printing and computer vision applications.  These high-contrast tracking markers are perfect for robotics, augmented reality, and positioning systems where durable, physical markers are required.

The model files are pre-scaled as 2.5x2.5 cm markers, but you can easily scale them in your slicer to any size you need. Just be sure to scale only along the X and Y axes so the thickness and color-change layers remain the same.

Feel free to download the 50, 100, 250 or 1000 .zip files or try one of the stand alone .step

Features:

• Dual-Body STEP Files

  • Designed with two distinct bodies per marker (one for each color), making multi-material setups or slicer color-blocking easier.

• Easy Orientation

  • Features a subtle orientation mark in the top-left corner so you always know which way is up.

• Built-In ID Labels

  • The specific ArUco ID is written on the back of each marker for quick physical identification.

• Efficient Printing

  • Optimized to require only a single filament change.

Print Settings:

• 0.2mm layer height

• Base layer -> white

• Second layer layer -> black

• Use opaque filaments for best detection results

• (Optional) Ironing the top-most layer

Note: Files are organized into convenient .zip packages (containing the 50, 250, 500, or 1000 dictionary sets), or you can download individual standalone .step files to test.
