Anet A8 Y belt tensioner for toothed idler
thingiverse
I just rebuilt the tensioner component to enable me to use toothed idlers that are slightly wider than standard idlers. *UPDATE* I've added a new 11mm wide idler version in response to Shiftah's request. You can find all other necessary parts and instructions on the outstanding Anet A8 Y Belt Tensioner page, courtesy of CH35C0.
