I am uploading this model as part of a demonstration of the power of volumetric representation. Models using voxel-based structure are known for having a large memory footprint and being difficult to process, but in the case of models with a very large amount of surface area such as fractals or the lattice structures often used in 3D printing, the volumetric structure has many advantages over polygon formats like STL. The original voxel dataset is presented here as a sequence of PNG images. I further processed the data to a more manageble size, filtered out noise, then generated a polygon mesh that can be produced with 3D printing.

For further explanation, please see my blog post on why this is important, called "Voxels vs. Polygons":
