Reinforce the base. Improve alignment. Upgrade foundation.
Replace the bottom‑left frame extrusion of your Ender 3 with this premium upgrade kit — designed to strengthen the left side of the printer’s base, maintain perfect frame squareness, and reduce wobble or misalignment during prints.
Key Features:
-
Precision left‑side profile extrusion: Specifically engineered for the bottom left corner of the Ender 3 frame, matching existing mounting holes and ensuring proper alignment with power supply and bed carriage.
-
High‑grade aluminium alloy: Built for minimal flex, strong structural support and longevity — helping maintain print accuracy over time.
-
Frame foundational upgrade: Ideal when you’re upgrading other components (e.g., motion system, springs, large bed) and need your frame’s left base corner to hold up.
-
Direct swap install: Easily remove the factory left bottom extrusion, install this upgraded profile with included hardware, ensure the base is square, and you’re ready to print with a stronger foundation.
-
Supports better print quality: A more stable base means the gantry, bed and axes align more reliably — less frame flex translates into cleaner prints, better first layers and fewer alignment issues.
