This isn't a prop but a good idea for any body who wants a good camera case. This is a water, drop, and dust proof box that I picked up from my local army surplus store for only $10. you can find them online for cheap or use something similar.
from there I went and bought some spongy foam blocks and cut out the size that I needed and glued them in to the box. from there its simple all you have to do is trace and cut around your camera and your done.
