the scissor chair

embraces limitations

of a 2-1/2 axis CNC router by using only orthogonal cuts in a design based on a specific non-orthogonal geometry
The chair privileges the top projection: by defining its geometry based on a consistent pattern, particular types of self-interlocking intersections occur
Early studies of the non-orthogonal glue-free joint
Generation of the primary profiles; parametric variations that would have resulted in different connection logics
