I bought the Creality Ender-3 V3 light bar kit for my Ender-3 Pro, but it was too small to mount properly. I designed a simple adapter in Fusion 360 to solve the problem. The model includes the cross-section for proper fitment and mounts to the 2020 extrusion using T-nuts. Installation requires 2× M5x20mm bolts and 2× M5x10mm bolts.
