Looking for Timing Belts? Look no further.

This OpenSCAD script allows you to generate a wide variety of parametric timing belts with customizable profiles, dimensions, and tooth configurations. Supporting industry-standard belt types such as MXL, XL, L, GT2, HTD, T-series, and more, this script is perfect for designing custom drive systems, 3D-printed mechanisms, robotics, and automation projects.

All attached print profiles were generated using the Belt Generator and are configured to match the specifications of the timing belts available in the Bambu Store. Note that some belts (tiny ones) may not be ideal for printing.

Click on Customize to open the generator.

🚀 Quick Start

1. Select a Belt Type

Choose from a variety of timing belt profiles, including MXL, XL, GT2, HTD, and T-series. Adjust key parameters like number of teeth, width, and tooth placement (inside, outside, or both sides).

2. Customize Your Belt

Each belt type comes with flexible options:

• Belt Shape: Choose between loop (closed) or straight (open).
• Pitch & Backing: Override standard values to customize tooth spacing and backing thickness.
• Teeth Configuration: Select if teeth should be on the inside, outside, or both sides of the belt.

Standard values follow industry specifications, but custom overrides allow for unique designs or make them easier to print.

3. Render and Export

Generate the belt and export it for slicing. It is recommended to print with TPU for flexibility and durability. Use the recommended print profile settings or fine-tune for your specific needs.
