Sectioned Menger and Sierpinsky with Support

thingiverse

The menger sponge prints without bridges And some Sierpinsky files... Menger: if it's corner is printed at a 45-degree angle, only the issue is that it falls over so three fins along edges must be placed to hold it up, or halves can be chopped in the middle and printed, which is what was done for this one; a perfect ABS menger sponge with only one perimeter and one top bottom layer, except it's sectioned. Sierpinsky: 1/ a sierpinsky triangle dominates the inside space like a big pyramid 2/ some sierpinsky files were edited to add Sierpinsky support for printing a precarious object (connected by three points in the middle) sierpinsky support are three fins that hold the sierpinsky at its tip so it logically can stand with triangles upright on their points; non-warping plastic is best because an extruder will brush against a big triangle's top if warping occurs. fifteen centimeters high and halfway to completion with 15cm tall fins, the ABS print succeeded with three attempts. placed seven sierpinsky support and Sierpinsky edit files together in slicer, positioned with two-dimensional view. The corrected sierpinsky opens perfectly now in sketchup etc so it can be placed correctly with support, then saved as one STL file.
