The prompt
The beam width looks ok. But I need to connect 4 such beams together. Two beams are 160cm long with a 90-degree cut and should stand vertically in parallel. The distance between these beams is 193 cm, including the beams' width. On top of these beams, place two other beams that are connected at a 135-degree angle between them. Beams are cut at 22.5 degrees at the connection point. The other end of the top beams should sit on the lower beam (160cm long ones) ends. Design an appropriate cut. Also, design an appropriate length of the top beams.
