About: Hello, I'm Bruce. I'm a student in Belgium. I have a wide variety of interests: electronics, computers, technology, ... In my spare time I spend a lot of time on: projects, exploring the internet, cycling. ht…

When I needed to make a pulley for a sumo robot I was building. I didn’t quite find the all in one solution I was searching for, I just needed the DXF of a specific tooth profile for a specific number of teeth.

So I could import this in Fusion 360 to make the custom pulley I want.

I found out about a parametric pulley designer on thingiverse http://www.thingiverse.com/thing:16627 but I couldn’t edit them in Fusion 360 to my needs.

I found a workaround on a site: http://rasterweb.net/raster/2012/07/16/openscad-t... .to export the tooth profile as a dxf.

And I simplified the complete workflow into one scad file. So you could easily generate a custom pulley with a specific: number of teeth, tooth profile and shaft diameter.
