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?
We are happy to announce the next evolution in the UltiMaker 3D printer lineup: the UltiMaker Factor 4 industrial-grade 3D printer, designed to take manufacturing to new levels of efficiency and reliability. Factor 4 is an end-to-end 3D printing solution for light industrial applications
Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
