sprockets for AndyMark chassis

[rhelber]

Is there a way to get a CAD or step file for PTC Creo of a sprocket that will go in an AndyMark chassis?  Or, do I have to make one?  Making a sprocket seems complicated.  If I can't get a file, is there a good tutorial for making a sprocket?

Model it as a disk for now and I'll do what I can to get you a comprehensive set of sprocket models.

Thanks!  Okay, I'll use disks.  I found a sprocket in a step file of the old AndyMark chassis.  But my team is using sprockets with a different number of teeth.  I like PTC Creo, it runs better than Autodesk Inventor on old slow laptops.

I found sprocket CAD files at VEX Robotics:

Thanks!  I'm all set.

These files are perfect.  Much better that the random .step files I found on the internet.  Thanks FRC Team 525!
