This is my version of the Chinook CH-47. It features a deployable landing gear and a rear door that opens and closes. It is very easy to print and does not require support settings.

Two small crew members are also included: a pilot and a soldier. Print as many as you want; after all, the Chinook can transport an entire troop!

STL and 3MF (for multicolor) files included.

No supports needed, make sure you have good adhesion to the print bed, if necessary use an additive, in my case I use a bit of strong hold hairspray.
