Wood box for 80mm glass sphere

thingiverse

I picked up an 80mm glass sphere for some projection experiments. But then I started thinking, this thing could be a real hazard if left sitting out in the open. Just one beam of direct sunlight could quickly start a fire on whatever surface it's resting on. So, I came up with a simple solution to keep it safe and secure - a wooden box that can shield it from stray sunbeams.
