Anet A8 Vertical stabilizer frame (CNC cut)

thingiverse

This is a custom-designed vertical (XZ axis) stabilizer/stiffener frame specifically tailored for Anet A8 printers. The XZ axis is notoriously the least stable axis on this printer model, and its geometry has been poorly optimized from the start, with no perpendicular stiffeners to support the vertical plates. This innovative fix addresses these issues. This design requires CNC cutting technology to bring it into reality. Thicker, stiffer materials are recommended for optimal performance, and I personally used 18mm plywood for this project. Note that there are two minor bugs in the current model: It's slightly too narrow, so you'll need to loosen the screws on the original frame, drill through the vertical posts into the stabilizer frame, and then re-tighten the original screws to eliminate any play. Additionally, the Y-axis threaded rod won't fit properly due to its design, so you'll have to file down some of the frame to accommodate it.
