Canvas Elbow radius + full ring variants

I really don’t like having to do 4 separate pieces just to do this.

Also, the radius setting on elbows is not correctly named, it should be labeled thickness, and elbows should also have a radius setting so we can get tighter funnel shapes.

The image above is the smallest you can make the hole in an elbow, but you can get the hole much smaller on a torus, because you can lower the total radius whilst maintaining thickness:

I actually made a suggestion for this on the steam forums BUT with the opposite direction facing for the elbow to allow easier making of the Aircraft Cowlings.
