Many DIY 3D printer makers are using idler pulleys based on 3D Printed wheels. Inaccurate printed idler decrease printing quality and create vibrations since the outside diameter of the idler is not concentric to rotation axis. Other makers are using double bearings with stationary washers clamped from both side. This solution is not ideal since there is friction between the moving belt to the stationary washers. Our Dual BB Aluminum Idler Pulley is a simple and inexpensive solution for this problem. Use M3 screw to mount this pulley.
