The main feature of this one is the staircase on the first level that goes left, right, and back... fairly tricky to lay out and trickier to cut, score and actually fold.

This was the first model I did where I was careful to reverse score the appropriate lines on the side of the paper opposite the template; I used a pin to make small holes at each end of the line to be scored.

Those stairs are a mess of closely drawn lines on the template, and despite my careful planning I scored some of them on the wrong side. Everything came out OK in the end, but it probably would have been easier if everything was scored to fold in the right direction.
