Update October 12th 2022:Added V2 F3D file for remix.Update October 8th 2022:Added V3.Mounting slots are longer and thicker.Added ziptie slots for front left fan's wires. I haven't tested it yet.Update September 4th 2022:Adjusted duct mounting holes and reinforced fan screw holes.-------------------------------------------------------------------------------------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.
