Ender 3 Pro Satsana Duct Mosquito Clone Hotend

I created this thing based on Darky82's Satsana remix for mosquito clone, the Mellow NF Crazy. Darky82's remix is for Ender 3 V2 with BLTouch, and I remixed it to fit Ender 3 Pro without BLTouch.

I also add a fan cover as I find myself always accidentally touching the fan for no apparent reason. Currently Darky82's fan ducts sit a bit higher up the nozzle, I will fix that in the next iteration. However, no printing problems found so far, bridging is excellent despite the fan duct position.

Cable Cap is from the original, made by Erik Anastas. It is optional but I find it quite helpful to hold the fan cap in place.

Material

For materials I use the one in hand, Which is PLA. This is not quite ideal due to the high heat produced on the hotend. PETG or ABS is preferred.

However, I am happy to report that PLA held up stronger than I expected. I have been printing and adjusting retraction setting on my mosquito clone and printing for almost a week with little rest inbetween and I see no visible warp or changes.

One issue I find with Darky82's Satsana is for the mosquito clone in Ender 3 Pro, my heater core/thermistor cable bundle rests on the fan duct (due to the close proximity) and permanently gives impression on the duct. However, it doesn't affect airflow.

Updates

Version 2

• Lengthening airduct by 3mm for clearance ( Airduct now not touching heat core cable and blow directly under)
• Add cutout to ease access of inner mounting screw
• Add snap fit to fan cover
