This model was made to illustrate the principle of the double parallelogram flexure hinge. It allows the primary to move in one direction while preventing movements in other directions.
Should be printed in PETG because of its flexibility.
The dimensions of the hinges and the limits on the movement were tuned so the stress in the hinges will stay below what PETG can withstand.
Hinges should be printed with continuous perimeters. In practice that means at least two perimeters. Interruptions in the perimeters of the hinge will cause them to fail.
