Description
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
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.
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.
