Solar Walkway Light Diffusers

The file SWL_Diff1.stl requires supports to print properly. I did get a useful print with the thing without supports, but had to hot-glue the overhang part which was full of holes.
The file SWL_Diff2.stl is designed to print without supports, but I have not printed one yet.

Print in natural PLA or Polycarbonate; it needs something with good translucence.
