Printing a 45 degree pipe bend (support question)

How would you guys print a hollow pipe that has a 45 degree bend in it? I’m guessing standing up and with tree supports?

Anything else I’m missing as when I slice it, it doesn’t seem to create tree supports to support the 45 degree bend?

Thoughts?

Oops, it’s a 22 degree bend, not a 45.

You don’t, need any support. Place the bigger Diameter onto the printbed and add some brims.

I agree - upright on the bigger diameter should do. In case you can enable tree support with the “Support critical regions only” option, slice the plate and see if Bambuslicer added support somewhere - at least by this you print with a minimum of support material. But by the picture I would guess you need no support at all.
