Plywood Corsi-Rosenthal box 2025 v1

Working on something that's easy to make.  In the end, this one is not quite what I'm after so I'll have another go another day

12mm plywood:

• Two pieces of 280 mm x 180 mm
• At the bottom: 395 mm x 180 mm
• At the bottom, the same but a rectangle that was cut out of the center that was way too hard
