This hotend assembly enables the use of a Noctua 4010 fan as for cooling the heat break and two Sunon 5015 blowers for part cooling.
NOTE: ALL FANS LINKED BELOW ARE 12V, THE ENDER USES 24V! PLAN ACCORDINGLY AND EITHER STEP YOUR VOLTAGES DOWN OR RUN YOUR FANS IN SERIES!

Sunon (NOTE: THESE FANS GENERATE A FAIR BIT OF NOISE, BUT HAVE EXCELLENT AIR OUTPUT. IF INTEREST IS THERE I MAY UPDATE THIS LATER WITH SOME QUIETER FAN OPTIONS):https://www.digikey.com/en/products/detail/GB1205PKV1-8AY.GN/259-1317-ND/1021167?utm_medium=email&utm_source=oce&utm_campaign=4251_OCE21RT&utm_content=productdetail_US&utm_cid=1860237&so=69804938&mkt_tok=MDI4LVNYSy01MDcAAAF9MUeK2VuqahYQJF7cqpXIW4CWAh9RqnGarVKJheQdvxcs6ZmKprQH9gyV9_Eiu6hEcNGQOiXoyycg1o7kZKzVPxHVEtZA1AgfbPw1W4P-
Recommended print orientation is shown in the photos, and supports from buildplate to all 45* overhangs is recommended.
To assemble, place the hotend wires through the righthand side of the main body, then bolt the hotend and the main body to the x-carriage. Place the two blowers in their respective slots (retaining screws optional). Screw the Noctua fan onto the front. Slide the wire retainer over the bundle of wires at the top. Finally, slide the fan ducts up inside the blowers; a drop or two of hot glue on the exterior of those is recommended to keep them from sliding out.
This assembly closely imitates the Hero Me suite of cooling systems found here, and credit goes to them for the original design: https://www.thingiverse.com/thing:4460970
