Sphere Box
thingiverse
The hollow sphere is made up of two printed pieces that fit together seamlessly. I've been printing it in PLA with supports, placing the "legs down" to ensure stability. The result is a snugly fitting piece that doesn't appear to be prone to falling apart even after repeated use. However, it did take some trial and error to get it right, as initially it was difficult to open and close easily.
