737 jet exhaust nozzle

thingiverse

This object is an inner exhaust nozzle extension to make the 737 engine look more like the real aircraft. It is inserted from the hatch where the Fan is installed and slid back into position. Mine was installed while the fan was out. While the fan is out you can also paint the front inner duct silver. The one in my AL37 fits tight without any glue required and has not come loose yet. It should be printed with the rear end on the printer platform and funneled portion up.
