The Absolute BEST dual fan duct!
Now capable of 200 mm bridging!!
Both fans are pressure fitted, just snap them on and they are good to go.
The air current is directed straight onto the tip of the nozzle, hardening the plastic as soon as it leaves the nozzle, while maintaining the hot end temperature!
This is a remix of several great designs, of which I took the best and polished to near perfection.
- The model is to be printed upside down (the air canals should be at the top) with supports.
- Some hot ends are really close to the heat block, and some height adjustment may be needed
Please print the first layers slowly or with a brim, the base is not very wide and needs to have a firm grip.
