Ender 3 pro fan duct with led and BL touch

thingiverse

I found myself needing room for the BL touch and LED lights and still wanting good cooling. This design brings the BL touch very close to the nozzle and accommodates two 40mm fans for good cooling. I run the hot end cooler blowing outward "away" from the printed parts. The design is meant to have 3mm brass melt-in inserts where needed for the fans. Optional spacers for getting the BL touch low enough. I use springs just in case there's a collision. Print the duct with supports everywhere and mounting face on the bed.
