Well I've been making this for about a week now, it's made from foam-board, poster-board, some tubing, and a lot of wood filler. It still needs some work, let me know what you think.
Ok so the mold came out sorta good, I might have to re-mold the scope. But anyway I cast one (I'll get pics up later) and I was cleaning it up with an x-acto knife, putting a little too much pressure on the knife causing it to break and go abuot 1 cm. into my big toe:
