737 jet exhaust nozzle

thingiverse

This extension nozzle is designed to mimic the genuine exhaust system of a 737 aircraft, giving it a more authentic look. To install it, simply slide it into place from the hatch where the fan is housed, ensuring it's properly seated. Since I installed mine with the fan removed, I was also able to give the front inner duct a fresh coat of silver paint while the opportunity presented itself. The AL37 variant fits snugly in place without requiring any adhesive, and so far, it has remained securely fastened. For optimal results, print this extension nozzle with its rear section oriented on the printer platform and the funnel-shaped portion pointing upwards.
