Print in PETG, ABS, or Resin.
I used tree supports above build plate. You can also use a brim if you need it.
The original duct had great fitment and clearances all I did was stretch the ducts to better cover the hot-end. as a proof of concept this worked great.
I will be refining this to create a bit of turbulence and will off center the ducts a bit for more complete coverage around the nozzle.
This is my first attempt a remix ever.
