Datsun 240Z fresh air vent ducting

thingiverse

I have designed a pair of fresh air vent ducting for the engine bay in a Datsun 240z. I printed mine in ABS but PETG should also be sufficient. If all you have is PLA go for it. I printed mine with 100% infill and support material just touching the build plate. I did not use internal supports. Feel free to experiment ot see what works best for your printer and material. Using either a brim or rafting is also probably a good idea. The footprint of the part alone is not very big. I have played around with the tab trying to get it to lay flush so it would not flex and possibly crack. This might change from car to car. Be careful when tightening the screw. Using a small thin rubber washer between the plastic tab and the car might help with any misalignment. Maybe even just cut off the tabs and use a small metal angle bracket like the stock ducting uses. Hope you like it.
