Not a question. Just a side tip.
I've been playing quite a bit with 3D printing recently and have to go back and forth with world settings because of regular work (not changing world scale for that, but do enjoy not having to do the conversions).
So I took a page from a completely unrelated course in Grease Pencil, DRAW, and made a custom 3D Printing template so I can get that all taken care of to my liking every time I'm tinkering with real world objects.
Here's the link to the lesson:

Thought I'd leave this tip here in case it can be useful to someone else.
