Parametric Timing Belt Generator (Makerworld)

Thanks to @lw9782 (Creative Inertia) for figuring out how to implement pattern features into the new bambu/fusion360 parametric tool!

Description

Parametric Timing Belt Generator

Summary

Create custom-sized, closed-loop timing belts with this fully parametric generator. Perfect for any project requiring a non-standard belt size, this tool lets you define the precise length, pitch, and tooth profile for prototyping, custom machines, or replacing hard-to-find parts.

Key Features

• Fully Parametric: Easily change the belt's length, width, and tooth profile by editing a few simple parameters.
• Industry Standard Inputs: The design is driven by Pitch and Number of Teeth, making it intuitive to use.
• 3D Print-Ready: Designed specifically for 3D printing with flexible filaments like TPU.

How to Use

(Please be patient when waiting for it to load, the tool is a little slow to generate).

Adjust the User Parameters to define your belt:

• NumberOfTeeth: The total number of teeth for the entire belt loop. This is the primary way to set the belt's length.
• Pitch: The distance from the center of one tooth to the next (e.g., 5mm for HTD-5M, 2mm for GT2).
• BeltWidth: The overall width of the belt.
• BaseThickness: The thickness of the belt's backing material.
• ToothHeight: The height of each individual tooth.
• ToothTopWidth: The width of the flat part on top of the tooth.

Printing Recommendations

Print with a flexible filament like TPU (95A shore hardness is a good start) for best results.

• Infill: 100% for strength (although with small belts this wont matter too much).
• Orientation: Print standing vertically for best tooth quality.
• Supports: None required.

I hope you find this tool useful for your projects!
