So sometimes it's useful to have your own co-ordinate frame, and there's a few ways you can go about creating them. One of the simplest is to simply print out this sheet from my website and cut it out. So let's do that.
Now you need to fold it. Along the dotted lines. Then a little bit of glue or a staple.
Voila! My co-ordinate frame. A red one.
This is an exercise in which you can build a 3D coordinate frame by printing, cutting, folding and stapling.
