Fractal Icosahedra

pinshape

Summary Fractal icosahedra are calculated by OpenSCAD with precision. Print Settings Printer: Da Vinci 2.0 DuoRafts: YesSupports: Yes Notes: The "daughter" icosahedra are generated at precise points, where a corner of each daughter shares a corner of the "mother" icosahedra. For level 1 & 2 (the limit on my PC), I tested two mother-daughter ratios - 1:0.5 which is solid and robust, and 1:0.385 which is the minimum ratio for one solid object. The stl files are rotated to make flat faces bottom, resized to a radius of 50mm. See comments in the OpenSCAD source about size specs and rotation angles. Data was fixed using Microsoft Model Repair service. I created this fractal icosahedra using a budget FDM printer (Da Vinci), but found that facets facing downwards become dirty at fractal levels 2 or higher. One solution is to divide solids into two when generating, then remove supports and glue them together - a much better result. The switch "half" in the OpenSCAD source controls this feature.
