Generating pulleys for AndyMark Belts

I am attempting to create pulleys for a robot in a custom size, by 3D printing them. In Inventor, there is the option in the design accelerator to generate "Synchronous Belts", but I don't know how I would create a system which employs the belts from AndyMark (5mm pitch HTD) such as this. What options or other tools should I use to accomplish this?

Use this Parametric pulley generator and import the STL.

Re: Generating pulleys for AndyMark Belts

If you have problems with the pulley generator, you can alternately download the CAD for a COTS pulley of the same desired tooth count, get the 2D profile from that, and then extrude your own with whatever desired features and thicknesses you want.

A pro tip for 3D printing - to avoid using a bunch of support material that will gunk up your belt teeth, either omit the top flange or print the top flange as a 45 degree angled surface from the root of the tooth upward.

I use traceparts.com and then I edit parts in Solidworks for our needs, like holes for the bearing or hex.

Here you can find HTD 5M
