Review on 5-Pack Aluminum GT2 Timing Belt Pulleys With 20 Teeth & 5Mm Bore For Efficient 3D Printing by Ken Wilson

Revainrating 5 out of 5

Used these to sync my 3D printer z-axis screws

I used these to modify my CR-10s 3D printer to synchronize the z-axis lead screws. I attached them at the top of the machine and connected them with a belt and tensioner (3D printed). Works great!I used a 760-2GT-6 belt to connect the pulleys.

Pros
  • These are much stronger than the ones provided on my FolgerTech FT-5 printer.
Cons
  • The 20 teeth may be too few for some applications, leading to less precise movement
