3D Files: DZ01 Mobile Robot with Track

The DZ01 is a compact, fully 3D-printable tracked robot chassis designed for makers who want to explore robotics using affordable, easy-to-find components.
It’s optimized for hobby-level electronics such as the WeMos D1 Mini, DRV8833 motor driver, and HC-SR04 ultrasonic sensor, making it an ideal base for obstacle-avoidance or autonomous navigation projects.

Key features:

• Modular, screw-based assembly for easy maintenance and part replacement

• Balanced center of gravity for stable motion on various surfaces

• Compatible with standard TT DC motors

• Designed to fit small Li-Po or AAA battery packs

• All parts printable on 120×120 mm beds (no supports required)

Note: Tolerances are optimized for common FDM 3D printers. Depending on your printer, some parts may require minor adjustment.
