Acorn Porch Light Replacement Lens

This is a replacement lens for an "Acorn Porch Light" found on some RVs. The one I copied was from a Denali super lite by Coachman. The shape was tricky to model and needed to be split into pieces to make it printable. I didn't bother including the lenticular grooves on the surface, since the layer lines do the job of diffusion well enough.
I made a third piece to clip the two halves together, but glue would work fine as well.
