Light Lens for Broan Vent Hood

This is a light lens for the Broan vent hood over a cooking stove. I have bought several of these over the years and they always seem to get brittle after a few years. I decided to make my own and I think the result is pretty good. I hope this one made of PLA will last longer than the OEM ones I've been buying.

Erm, the underside of my hood is nasty due to a cooking fire caused by a person I will not name. :|
