The models were repaired and checked for printability.
Cross-axis flexure pivots are created by crossing flexures and connecting them with
...Show more rigid segments at their ends, allowing the opposite ends to rotate relative to each other. Cross-axis flexure pivots can replace pin joints in applications where wear and/or friction need to be low or eliminated.

Create your own cross axis flexure pivot by printing two Cross Axis parts, rotating them so the clips are on opposite ends and facing each other, then clipping the two parts together (see the images above). The two pieces should fit secure with the studs in each corresponding hole and the clips in place.
A version of the cross-axis flexure pivot, the Cylindrical Cross-Axis Flexure Pivot (CCAFP), has been proposed as an ultra-compact flexure capable of being integrated into mechanisms used for minimally invasive surgeries. This CCAFP would create a flexible, hollow wrist at the end of surgical instruments that allows for cables and other components to pass through the inside of the shaft. Potentially, this could decrease the instrumentu2019s size while maintaining the instrumentu2019s performance.rn
This cross-axis flexure pivot could also benefit any other application that would require compact and non-intrusive motion components.rn
A two-degree-of-freedom joint can be created by stacking two cross-axis flexure pivots with their axes of rotation orthogonal to each other.
