Mountable Y-axis PLA bushings

thingiverse

To simplify y-axis bushing replacement, I altered the provided instructions by using a 11mm length mountable bushing instead of creating excessive friction with a longer one. While installation might take time and accuracy in measurements for proper squaring, it ensures smoother future replacements. The given SCAD file is adapted from Prusa's original pla-bushing.scad with added mounting arms, compatible with the configuration settings in your Prusa scad. To avoid reaming, print bushings with a slightly larger rod size as defined in the configuration.scad file. However, be mindful of using the correct rod size when installing the STL provided. For installation, flip the printer onto its backside and place the bottom plate on the snapped bushings, resting on the bearing mudguard washers. Mark the inside of the mounting holes on the plate while keeping it square with the rods. Drill the marked holes and securely bolt the bushings onto the plate. Finally, ensure smooth movement on the y-axis rods and follow the Prusa build instructions. Remember to adjust spacing if binding occurs.
