Many users of our software do this on a regular basis. Making hollow parts
from STL files is straightforward (we call it "shelling").
I believe it is better to make the vent and drain holes in the STL model. With suitable
software tools, the geometry and position of the drain holes is up to you. In
addition, you can also manufacture the pieces that cover the holes one you drain
the resin and/or back fill it.
