This is a complete redesign of thing 4170231.
This is a complete fan duct for the Ender 3 style series of printers. Extremely compact and efficient and guaranteed to outperform any other single 5015 style fan duct. This is setup specifically to work with the Dragonfly BMS, and stock Ender 3 series hotends.
Final design is 60mm wide without BLTouch, and 80mm with.
Flow simulations and data aside, what I am most proud of with this design, other than its excellent airflow and cooling, is that it is specifically designed not to alter default offsets from the stock fan shroud, at all.
Extensive testing also proved that printing a 15 minute Benchy suffered no lack of cooling!
Supports: Touching BuildPlate Designed for 30% infill but use whatever youd like.
