Sectioned Menger and Sierpinsky with Support

The menger sponge prints without bridges And some Sierpinsky files...

Menger:

if you can print it on it's corner as all angles are then 45 degrees, only issue is that it falls over so you have to place 3 fins along edges to hold it up, or you can chop it in the middle and print halves, which is what i did for this one, perfect ABS menger sponge with only 1 perimiter and 1 top bottom layer, except it's sectioned.

Sierpinsky:
1/ a sierpinsky with a big triangle in teh middle, like a pyramid

2/ some sierpinsky edit and sierpinsky support files to print the complete precarious print (connected by only 3 points in the middle)

sierpinsky support is 3 fins that hold the sierpinsky on it's tip so it logically can print all the triangles standing on their point. probably best with non warping plastic as you dont want the extruder brusing the top of a big triangle whith warped top. I got over half way with the fins and 15cm top balanced sierpinsky on the first attempt in ABS. placed the sierp support 7 and sierpinsky edit 1 file together in slicer and positioned with 2d view.

The sierpinsky is a corrected version of george heart websites one, and now it opens ok in sketchup etc so you can position it with support and save as 1 stl.
