Summary Fractal dodecahedra calculated by OpenSCAD. Print Settings Printer: Da Vinci 2.0 DuoRafts: YesSupports: Yes Notes: The "daughter" dodecahedra are generated at the point so that a corner of daughter shares a corner of "mother" dodecahedra. The stl files are generated with (mother:daughter) ratio = (1:0.279) (minimum ratio that the object be one solid). The OpenSCAD source generates the shape with radius 1.0mm. The stl files are rotated to make the flat face bottom, resized to radius 50mm. See the comments in the OpenSCAD source about size specs, rotation angle. Fixed data using Microsoft Model Repair service. I made it using cheap FDM printer (Da Vinci), then found the facets facing to the bottom becomes dirty, at fractal level >= 2. One of the solution is, divide solid into two when generating, later get rid of supports and glue - rather better. The switch "half" in OpenSCAD source controls this. Still the radius = 50mm is too small for 2nd level daughter, not so beautiful.
