🚀 Quick Start

1. Select a Pulley Type

Choose from a variety of timing belt profiles. Adjust key parameters like tooth count and pulley width to match your belt specifications.

2. Customize Your Pulley

Each pulley type offers configuration options:

• Flange Configuration: Choose whether your pulley has no flanges, a top flange, or both flanges for belt retention. Adjust flange height, thickness, and taper to suit your needs.
• Bore Type: Select the bore type, including cylindrical, keyway, D-bore, or hex, and customize its dimensions for a precise fit.
• Hub & Mounting: Opt to include a hub for additional shaft support. Configure set screws with adjustable diameter, position, and count to ensure secure attachment.

3. Render and Export

Once customized, generate the pulley and export it for slicing and printing. Enjoy!
