The gt2 pulley with 20 teeth or grooves is one of the best choices for 3d printer construction. Compared with the T2.5 or MXL timing pulley, the gt2 pulley tooth profile is anti-backlash. Why? The rounded teeth of this tooth and belt are engaged together longer providing a smoother transition between teeth. This is what you need for your 3D printer. A smaller pulley with less teeth moves less belt per revolution. Not great for printing speed but with a 200 step motor and a 20 tooth pulley that means every single tooth on your belt can move in ten discrete steps! That’s going to make for some really nice prints!
Specifications are as following:
