You are too close
When working with the classic combination of laser cutting and bending of sheet metal there are rules to follow. I think I know most of them by now, but you never know for sure. One rule is don’t put a hole too close to a bend as it will get stretched. That is what happened here. The stretched and partially un-bent result is actually beautiful and soon found a purpose too.
When you bend sheet metal close to an opening it pull it into shape.
Material properties dictate form – the bending performance of the metal is very poor, bu the results are very good and surprisingly useful.
It turned out that the resulting hole creates a perfectly shaped anti-slip footrest. It got used on one of my bar stools and it is one of those occassions where you get a complex result with very little effort which is the essence of industrial design thinking.
