Seeing tc_fea's Taj Mahal inspired me to upload this version that I printed a few days ago. I found a model on google warehouse and simplified it to make it printable. I didn't hollow it out but definitely should have. This thing is big, too big for a makerbot. It took up most of my prusa platform and took something like 12 hrs to print even with very low infill.
Print with very low infill and it will still take forever.
