    3mm HTD Timing Pulley Profile

    1. As I said above, I found a 3-D model of the correct pulley. 2. As I said above, I'm making a rapid prototype of it so it needs to be completely accurate. 3. No, it's not a school project.

    3mm HTD Timing Pulley Profile

    3mm HTD Timing Pulley Profile

    I'm looking for dimensional information on the tooth profile for a 3mm HTD Timing Pulley. I've looked all over and can't find that detailed profile info. I'm making a custom part that is going to be rapid prototyped so I need the teeth to be exact instead of just represented for a drawing...
