Original model is
Ender 3 | Dual 5015 Fan Duct by Simon_Szi_
I modified below.
1, I added a mount for CR touch. (close enough to the genuine CR touch mount location)
2, Enlarged mounting holes so that we can adjust the fan height up or down.
3, Added Hero Me style mounting clip for more stability. (3rd mounting place to the gantry)
4, Added space around the 4010 fan area for wiring routing.
5, Filled weird empty space inside the fan duct.
It fits my Ender-3 PRO perfectly and it won't hit the X axis end stop sensor. I printed with PETG 0.3mm/0.6mm, 10% infill with 3 walls.(Simon_Szi_recommends 30% infill or higher, but I reduced to 10% to reduce weight) 0.6mm nozzle. Needs 3 x M3 brass insert nuts. I used 4mm long, 4.5mm width one.(same as Hero Me)
