No problem. I will print one for you. PM me your address and I will get one over to you.
What have you 3D printed for your TJ?

Yep, those were definitely printed (probably with supports).
Windstar air intake adapter.
Unblended polycarbonate, so it's good for all underhood temperatures up to about 300°F. All but the thinnest sections are 20% infilled to add thermal decoupling to the underhood air. Most of the tube is also able to be insulated.
Interior (not visible in photos) is very smooth and curved to allow as little airflow restriction as possible.
Took 12 hours to print. Had the heated chamber up to 89°C, bed temperature at 155°C, extruder at 320°C, 100 mm/s on all print settings.
Did have one blob of death start, but fortunately the part broke free and I woke up to spaghetti instead. Even though that print failed, I did get to see just how strong it was. Could not break the tube even by stomping it with my boot.
Pure polycarbonate prints like PLA once you get the temperatures right.

You might find these posts interesting, though I have a sneaking suspicion your 97's fresh air opening in the cowl looks a little different than mine...

Heat, heat, and more heat is the best way to print polycarbonate. If you can keep much of the part at an annealing temperature, it basically self-anneals as it prints, so no warping.
My next challenge will be to re-print the hotend in Ultem, since the fan shroud has already mostly melted...
Where are you placing your intake? You could squeeze this in a smaller package with a shorter snout. Do you have any indication of how the air travels with the sharper edges vs the Windstar OEM?
Basically copying the traditional placement. The snout is long enough to make it to the elbow, and keep the intake pipe in its current position (perpendicular to the engine).
The internal edges are actually way more smooth in mine than in the Windstar intake second half, especially after that piece is cut in half and shortened. The internal diameter starts at the diameter of the air filter outlet and then follows a smooth curve to taper down to the diameter of the factory intake tube, allowing me to use a standard 2.75" elbow.
Hard to tell in those photos, but the wall thickness varies dramatically through the part. At the base, it is 0.3" or more thick, but by the time it terminates at the elbow, it is only about 0.03" thick.

Thanks! It does look like the same shape and all… would you be willing to print and sell these? Or perhaps just share the design files? I think I know someone locally who would print it for me. What material did you use/suggest?

My printer's pretty quick but I don't really have the capacity to print and sell them. As well, I'm not looking to deal with product support in the traditional sense....but the print files are available for download. You'll find a download link in this thread:

I would recommend ABS or ASA for the filament. PLA is a very common and inexpensive filament but isn't suitable for this application.
TPU will work as well and is easier to print than ABS - see Ninjatek Armadillo for example. Andy
No unfortunately, never heard back… if you find some or anything PLEASE let me know
