Csaszar polyhedron

thingiverse

The Szilassi polyhedron's dual is a polyhedron with a hole and a minimum number of vertexes greater than zero, modeled by cdsteinkuehler and published on August 22, 2012 at http://www.thingiverse.com/thing:29014/#files. It has already been printed. The uploader does not own a 3D printer but shared the design for fun. They hope someone will print a working puzzle of either the hole and two halves or seven tetrahedrons. For this, they require TextGenerator.scad by pgreenland (http://www.thingiverse.com/thing:59817/#files) and maths.scad by William A Adams (https://github.com/kweekly/sensezilla-hardware/blob/master/dust_environment_sensor/enclosures/bezier_test/maths.scad). The uploader requests top, bottom, left, right, front, and back orthogonal views with or without animation for a pretty result. They have exported an STL file of the main solid to Blender and used UV mapping to mark seam on 17, 14, 45, 52, 62, 51, 74, and 73 edges, unwrapping it into a PNG unfold pattern. After printing and painting the paper model they downloaded, they realized using SVG format in Inkscape would be easier. Unfortunately, they didn't print the final cut of paper with extended margins for glue.
