NASA Handrail Clamp (Version 1.1)

In "Forces on a Wedge," I was inspired to further develop my previous version based on the same principle for securing a handrail. A wedge is applied to create clamping force between the handrail profile's planar surfaces. To assemble, follow the direction of the wedge along the length of the handrail, in the sliding direction of the clamp itself, on one side of the handrail profile. An optional adjustment screw is available for finalizing the wedge position, while an alternative option includes a handle pin to move the wedge between locking and unlocking positions. This concept has yet to be tested using 3D printing, so it's uncertain whether it will work as intended. Other design concepts seem more user-friendly, but I sought a solution for a design without radial bending features. Dimension tolerance compensation is relatively easy due to the use of a wedge only.
