FWIW, replacing the lenticular is not as easy as you might think. The
lenticular screen is attached to the fresnel screen in a specific way so
that the fresnel screen is allowed to hang freely, which prevents it
from bowing. It's very easy to get small bits of debris in between these
two screens when assembling them, which can make visible shadows on the
screen.
