4' x 4' staging unit steel frame at a scale of 1:25.
The outside dimensions are perfectly accurate, I took a few minor liberties with the detail in order to make it a viable print. Add a piece of 0.8mm aero ply or thickish card for the top and slot in cut-to-length 2mm dowel for the legs. (Trimmed cocktail sticks or toothpicks will suffice.)
