One thing I forgot to mention is that you need to
make a guide for the two mold halves to fit together.
This can be made of clay.
Four nubs with a ring going around the lamp piece.
as seen here.

Here you also see brushing on the release agent.
You must put this on all things the rubber will touch.
That is the piece to be molded the sides of the box (inside)
And the clay joints.
So the rubber will not stick.
