Just type in 20DP - 14.5 PA and the tooth size you'd like. Download the model and modify to make an AndyMark gear. Unsure if there is another online database of AM gear models. I'm sure you can email AndyMark and they would be more than happy to send you the models.

Can you give an example for input? I may have misunderstood you because I got nothing after several attempts. Thanks!

So for this gear the pitch diameter would be 12/32=.375" and the outside diameter would be (12+2)/32=.438"

Hope this helps. In large assemblies, especially on lower end computers, it is better to make simplified representations like this and allow for the resources to be used where needed.

I will start with this. Thank you!

Maybe I should've mentioned this: I'm trying to design a gearbox with an random ratio and no purpose, to gain experience in gearbox design.
