i got a cheap prusa copy 3d printer. I'm trying to print gt2 pulley but don't think the teeth are deep enough. The timing belt just slides over, are there any good settings for printing pulley or are there any models with deeper teeth? all tips are welcome

You can makes some really really nice GT2 pulleys very easily in openSCAD which is free, open source, and light weight.  You won't have to learn openSCAD much since you won't be desigining in there - just using it to make pulleys.

 

I'm not certain where the library came from but here are some major hints at the top of the file:

You can set things like number of teeth, pulley type (you want profile=12), shaft diameter and many others.

 

I've made several GT2 pulleys and right now am only using one of them with 200 teeth but these fit the belts very nicely and should work fine at a mere 40 teeth.  Maybe less.  Maybe only 20?

thanks for the answer, but think you misunderstand me. I don't get enough good printed pulleys, the teeth are too shallow

      Through this post I would like to further explain what we are doing, and what you could be doing. 
      Our efforts consist of 2 layers. First; connect medical institutions and hospitals to (local) 3D Printing hubs to help them print parts of which a 3D model already exists. And second, contribute to design the necessary part and then have it printed via a (local) 3D printing hub. Experts are available from within Ultimaker and from within our network of 3D printing experts.
