Tuber
thingiverse
Cool looking crisscrossing tubes. I've seen people print things similar to this before but have not found the file for it, so I made my own. It printed on a Fablicator with KISSlicer in 4.5 hours. Instructions The .stl is approximately a 7x7x7 cube. Use RepG and scale it accordingly to fit your printer. Prints well completely hollow. With 2-3 shells it could probably hold a fair amount of weight. Best to make this from PLA. ABS will likely warp too badly if you print it near full scale.
