Fan duct Ender 3 Pro

thingiverse

I was getting really bad stringing on my pro 3, even though I had cahnged a lot of setting. I tried a few other fan ducts butstill same results. As i didnt want to cahnge my entire hot end fan system, i made this duct to fit on the oem parts. I did a few different versions but in the end this one came out really well. I re callibrated my ender 3 pro, from the flow rate to e-steps to x, y and z movement. After that and running this new fan duct... I got results you see in the pics. Running a stringing test i had 0 stringing, was very surprised but also very impressed.
