BMG/V6 Linear Rail Carriage

thingiverse

This is an X axis carriage that mounts directly onto a linear rail, specifically one I designed myself for my Ender 3 printer. It utilizes a direct drive BMG extruder and a pancake stepper motor, which provides efficient movement. To keep the stepper from overheating, I incorporated a fan duct using the original part cooling fan, as there's not enough space for a heat sink. The belt attaches securely via clamps located at the bottom of the carriage. When assembling mine, I routed it through a hole before locking it into place with the clamps, ensuring the belt remains straight and evenly tensioned. As the design has undergone numerous revisions over time, I anticipate making further adjustments in the future to optimize its performance.
