A parametric, hermaphroditic, snap-together hinge.

Two identical parts will snap together to form a complete hinge. Can be used as an actual hinge, or for assembling polyhedrons from a set of individual faces.

tabs: number of tabs (and gaps) in one hinge piece thickness: height of hinge (the diameter of the pivot is derived from thickness) length: length along the hinge pivot leafWidth: width of the hinge leaf (excluding the pivot) clearance: distance between two connecting surfaces (reduce for structural stability, increase for freedom of motion) swingLimitTop: limiting angle of the hinge when swinging closed (0-90 degrees) swingLimitBottom: limiting angle of the hinge when swinging open (0-90 degrees) bumpHeight: height of pivot bump (depth of pivot indentation)
