I don’t know if this is actually considered a practical cut, but it seems to so me.
In the Museum business, graphic interpretive signs are called “Labels” ( no matter how big they are).
I am installing a new exhibit & wanted a more flexible way to attach the labels to the 1.5" square tube I’m using as a crowd barrier. This is what I came up with, they simply snap onto the steel tube, can be slid horizontally wherever I want them, and the angle of the label is adjustable (the actual printed graphic is glued to a sheet of 1/4" sintex that is then attached to the bracket with velcro).
The first version of these was designed to be 3D printed, but each one took a couple of hours. The Glowforge versions print in less than 7 minutes & I have one completely assembled in 10 mins. They are made from 1/4" acetal.
Here are the parts:
