A topologically titillating twisted triple torus 😊

This complex model is better suited for resin printing, but it is theoretically doable in FDM.

A topology "hole through a hole in a hole" is equivalent to a three-holed torus or a triple torus (a surface with genus 3). This shape is topologically equivalent to a three-handled coffee mug, which can be visualized by stretching and reshaping a solid object, like a ball, after removing three intersecting cylindrical volumes, resulting in three connected, non-trivial, tunnel-like structures.
