Reciprocal Reuleaux Triangle for FDM

thingiverse

A geometric figure showcases a square enclosed within a triangular cavity, set inside a triangular solid featuring a square opening. The previous model displayed two interconnected triangles, each encased by a square hole. However, this design flawed due to a disrupted symmetry from the square hole within the triangle. It also failed to leverage the unique characteristic of a Reuleaux triangle that allows a square to fit into a triangular cavity. In line with its predecessors, the design incorporates an overhang angle of 45 degrees to ensure printability on FDM printers while maintaining part integrity through interlocking components.
