A 3d-model of the armpiece / wristpiece of the spacesuits seen in the movie Alien the model is made for easy printability and includes both parametric and mesh / STL files for printing this only includes the full piece but it's probably easiest to print if split in half top to bottom so you print two rings both with flat bottoms it is scaled to the other spacesuit pieces I made but can be scaled up or down and remain printable
