Menger Sponge
cults3d
A Menger sponge 3D Fractal, generated with a recursive and very short OpenSCAD script. The image is a rendering from Blender software. The STL file for the model with four levels of recursion was over 100 MB in size, which was way too large to upload. However, I've uploaded a Blender rendering. Using Cura software, I was able to print a cube about 30 mm on a side using its experimental "tree" supports. However, only files "menger_sponge_fixed.stl" and "menger_sponge3_fixed.stl" are proper manifolds. Cura is apparently very tolerant of non-manifold files.
With this file you will be able to print Menger Sponge with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Menger Sponge.
