Postlight3

This is a modification to https://www.thingiverse.com/thing:4236653. I applied a double twist to the straight ribs but was careful to allow tiny holes between them at the widest part of the top. The holes turned out to be too small (see the magnified image) so for Postlight4 (printing now) I've changed the shape of the top and made the ribs larger and farther apart.
