Only an Ork would try to sqeeze through such a narrow tube. It's a copper pipe with a bit on metal wiring. I made the rivets on the top using the green stuff rivet technique. The ring at the end is cardboard.
This guy is peeking out. I cut his face in half to make it look like he is rising up out of the dark.
The lid is made of balsa wood with some extra bitz laying around.
It's a simple but rewarding project and I can think of many ways to make different ones.
Hope it inspires you guys to make some as these as presents or to use in a game.
