Tips to Set Up Cardboard Box

1. Various cardboard boxes can be used but we have found 2 that are easy to set up: the medium-size Pack 'n Post shipping box from Clas Ohlson (335 × 250 × 110 mm) and the Brown Single Wall Dispatch Carton from Post Office UK (330 × 254 × 178 mm).

2. The light source can be any battery-powered LED torch; for our system, we used the “waterproof portable 24 LED camping light outdoor LED tent lamp with hanging hook,” available from online shops such as Amazon. This can be placed inside the box and taped to the side where the camera will enter just anterior from the camera cutout in the box.

3. The box must be securely attached to the working surface using C-clamps; 2 are recommended. The box is placed at the edge of the table or working surface along its long axis, and 2 openings are cut: one close to the camera side and one distal. A small clamp (e.g., the Screw Clamp from Clas Ohlson) is used to secure the box to the table proximal to the camera side. A larger clamp (e.g., the 50-mm Cocraft G-Clamp from Clas Ohlson) can be used to secure both the box and the sanding block distal to the camera side.
