Description:

General duct shape was inspired by Mini Satsana Neptune 2 duct fan.

I added a dado and a slot to run cable for the right fan on the inside of the duct.
Screws fit pretty loose for easy adjustment.

• Make sure to position the side ducts above the nozzle tip to allow proper leveling.
  Ducts are designed to float 1mm higher than nozzle's tip.

I found overhangs and support detachment needing improvement with the original duct.
The old duct also makes it very hard to see the nozzle and the first layer on smaller prints.

I recommend printing in PETG. I printed in PLA and it works fine.
Block some of the support in the ducts for easy removal. I let it print support 3mm from the edge.
Very easy print. Takes about 6 hours at 0.2mm and 4 hours at 0.3mm.
