I designed props to be produced from laser cut sheets of corrugated cardboard. Items included a sword, cauldron and an axe, which weaved layers to produce a 3D appearance. The cauldron was produced using a truncated octahedron net, with tabs to act as a stand. The items remained attached to the sheets using uncut slots, removal would simply require a craftknife. Assembly required a small amount of hot glue.
Images of the items are below:
