The reason for building a box out of foam core is to use cut film holders.
For your purposes there is really no need to do that, just use any hollow
container, cereal boxes, cereal cylindrical containers, show boxes, soda pop
cans, etc. Soda can material is OK to make the pinholes. For the shutter,
get a small piece of kitchen aluminum foil, stick it to a piece of tape
(duct tape, electric tape, etc). Stick the piece of tape on top of the
pinhole in such a way that the piece of aluminum is right on the pinhole
aperture, the aluminum will prevent the aperture to become contaminated with
the tape's glue.
