This is a fan duct for the original i3 mega part cooler fan & position.
It has 2 sides cooling tubes with equal length and identical cross sections.
The "exhaust" is tilted so the airflow hits right underneath the nozzle.
Clearance from the lowest point (exhaust) to build plate is around 2-3mm.
- has 3mm more clearance to the build plate, and a colar for fixation of the fan.
- corrected the colar for the fan, now it should fit in and sit tight. and changed the thickness of the colar to 1.2mm for better printability
--> removed the V2 from database.
Supports ONLY FROM BED, not on the part, else the tubes will be filled.
Print it "standing" up in operation Position.
