Ender 3 5015 Cooling Fan

thingiverse

The original creator left out a vital component for the 5015 fan model: a BLTouch. Filling this gap, I present to you this revised design. Other than the addition of through-holes for mounting the 40mm fan, allowing users to employ bolts of any length, no further modifications were made. The 5015 fan now securely attaches with one bolt, eliminating the need for precise bolt lengths. The front "triangle" was deemed unnecessary and obstructed airflow, so it's been removed. This design encourages printing the carriage upside down with supports, ensuring maximum thickness and a slow print speed. Given this part's importance, taking extra time to get it right is well worth the effort – you only need one perfect print after all.
