Lead Screw Bearing Block for CR-10

thingiverse

I wasn't thrilled with the factory lead screw bearing blocks on my CR-10, as they were excessively tight and seemed to resist movement if the alignment was off even slightly. To address this issue, I engineered these custom blocks to utilize 608ZZ bearings that can be readily sourced from AliExpress or Banggood. A small amount of silicone adhesive is applied to the insert face to prevent the bearing body from rotating within the main block. Existing hardware is re-used throughout the design.
