I have made a small tray with angled sides, of course in LightBurn 
My question is: Is there a program like Boxes.py, for example. that can “automate” the process? (btw. Boxes.py does not support angled sides)
If you also can’t find anything on the web 
, does anyone here know how to make this type of box relatively easily and reproducibly, also in other dimensions and angles? - in LightBurn.
(The version shown has been mostly a “try it and improve it” method)
Nice work! As you can see, those are non-90 degree angles for nearly everything. That would take some serious looping calculations to generate. The bottom tabs are okay, but maybe scaling the side tabs (not the ones for the bottom) and stretching the top using the Node Edit tool could work. Not much chance of getting around your trial and error method. Just so you know, a lot of engineering is done that way.
Here the same in 3mm BB plywood.
The fingers have been given 1.5mm extra length to compensate for the angles, a little sandpaper afterwards …
Did you make that or Photoshop his image? 
I think I’m better at LB than PS…
