This is a geometrically accurate Tetrahedron modeled in Autodesk Fusion360.The model is provided as two versions with either 0.75mm fillet or 0.75mm chamfer placed on all edges.Two gcode files are provided for each, a single model and triple model. The triple may print more easily as the increased surface area and brim helps to keep them joined together on the bed for the first critical few millimeters.Features:Side length = 60.0 mmSpherical void diameter = 26.0 mm (centered on the centroid) (your coin must be less than this.)Diameter of spherical void/ tetrahedron face intersection = 17.6 mm (Your coin must be greater than this.)If printing the triple gcode you can easily slip a coin into each instance without pausing the printer at about 13.7mm Z height.I used a NZD $0.20 coin which is ~21.6mm in diameter.Actual .step and .f3d files are provided if you want to adjust any dimensions, or make the edges or vertices less sharp so they are safer for little hands.
