Cooling Duct for Anycubic 4Max.
This duct is designed for a 50x50x25 blower fan.
There is a new version of it which is designed for the original 5015 blower fan:
There is no space for screw, so I made 2 holes to use ribbon to keep the fan in place.
The duct height is adjustable, range about 4mm, to get more accurate cooling target.
Other materials: 2xM3.5-10 screws, 1xM3.5-40 screw, 3xM3.5 Nuts
