ArUco Markers Generator

Parametric ArUco / AprilTag Marker Tiles

Fully parametric ArUco and AprilTag marker tiles, designed for two-color FDM printing without an AMS. All marker data is embedded directly in the OpenSCAD file — no external scripts or libraries needed.

Features

  - Supports 10 marker dictionaries: AprilTag 16h5, 25h9, 36h10, 36h11, ArUco Original, DICT_4X4_1000, DICT_5X5_1000, DICT_6X6_1000, DICT_7X7_1000, and MIP 36h12
  - Generate a single marker or an entire grid by setting a first and last ID
  - Fully adjustable cell size, quiet-zone margin, base height, and top height
  - Black base and white top are separate objects for easy color assignment in Bambu Studio

Printing

The marker is split into two parts at the base height:

  1. Export with render_part = 1 (Black base) and render_part = 2 (White top)
  2. Import both STLs into Bambu Studio as a multi-part object and assign your filament colors

No AMS required — if printing single-color, simply pause at the first layer above base_h and swap filament manually.

Customizer parameters

  - marker_dict — choose your dictionary from the dropdown
  - first_id / last_id — range of marker IDs to generate
  - grid_cols — number of columns in the output grid (0 = auto)
  - cell_size — size of one data cell in mm
  - margin — quiet-zone border width in mm
  - base_h / top_h — layer heights for each color
  - render_part — select which part to export
