Ender 2 Pro 4010 Blower Fan Ducts

I pieced together a hotend for my Ender 2 Pro and the stock part fan duct would no longer work for my needs. I designed these ducts to replace the stock ducts. YMMV on if it'll fit your printer or not. There is a tall and short version. The short version is 2mm shorter than the tall version. On my modified Ender 2 Pro hotend, I use the long version. 
 

If you have dual fans, a left fan version is supplied. I used a mount that The 300lb Gorilla designed for me to mount the fan along with the EZABL micro. To mount the fan on the left side, I drilled 1.5mm holes for the top holes and used M2 bolts. The duct mounted with 2 bolts with nuts on the bottom.

The right duct mounts with the stock M2 bolts threaded into the stock mounting plate. 

Print settings:

• Layer height: 0.2mm
• Infill: 20%
• Material: ABS
• Supports:  From build plate only. You mainly just need supports under the screw mounting points.
• Orientation: Print with the duct on its back against the build plate
