How do I close this opening? Maybe not understanding "draft"

StillMaker

I'm trying to close this opening marked in the screenshot. Maybe draft is not the right tool here? I want to close it at the same angle that I've created with the sides, using the draft tool.

Thanks for any help.

Make that whole side protrusion as a new part, not an add part. Angle the bottom face. Then shell it. Then union it to the main part.

You may like this with a move face. One of a couple ideas that comes to mind.

Looks great, thank you!

Hmm actually the key @glen_dewsbury was what you did with Extrude 3, setting an offset so it stops the extrude before it goes all the way through. Once that is done, a move-face or a draft works. But it ends up as a solid, I would like that new triangle area to be hollow since I am 3D printing this.

Is there an easy way to do that? If not I'll explore what @nick_papageorge073 suggested.

If you check in my sample, both the inner and outer face was selected for move/rotate leaving hollow volume.

Ah, I see now. That worked, thanks!

Here is the boolean union way:
