How to tidy up corner between chamfers?

After chamfering along an edge involving several components, there is a residual "nose" in the corner.

 

Does anybody have any suggestions as to how to tidy this up?!

Model is attached.

The timeline has been rolled back to before the "Bead moldings" component in the timeline.
Subsequent timeline items are not relevant to this subject.

 

This is a graphic from the publication relating to the design:

There would appear to be two alternatives to tidying up this corner:

a) Rounding with a fillet, to result in an appearance as in the graphic.

b) Continuing the chamfers so that faces remain angled with no curvature being involved.

 

I should like to try both, then decide which looks best

 

I can imagine that either (a) or (b) could be done with some sketches and lofting ...
but is there a simpler way involving some sort of removal of faces or similar approach?

In the Attached I present two possible solutions.

Many thanks.

That is an interesting use of the Revolve (at the right)!

 

---------------
For the version with flats at the left side,
it is an interesting use of Extrude ... To object ... where the "to object" is a sloping face.
I had assumed that the "to object" had to be perpendicular to the extrusion profile.

 

The version with flats would probably look better if an equal amount were to be "chiseled off" each of the triangular faces of the undesired residual piece, i.e., such that the chamfers meet in a continuation of their upper edges and the line joining the two moldings is symmetrical in relation to each sloping face.

 

I tried using a sketch on a vertical plane at 45 degrees.
I tried to produce an intersection point on that sketch for the upper edge of the long chamfer but no point is seen in my sketch.
Equally I tried to produce an intersection line on that sketch for the face of the long chamfer - but again nothing is seen.
Why is this?

Actually, thinking about it this approach probably does not provide a solution for subsequent extrusions in two directions as I was originally thinking.
Probably some sort of hole would get cut 😞

Thinking again about it, I realise that you already provided the symmetrical solution for the left side.
My first impression was that it lacked symmetry - but that is only because there is an extra line seen on the short face which results from there being two thicknesses of wood rather than a lack of symmetry.

 

I still interested in why I am unable to produce an intersection point or line on the sketch I was doing ...

Yes, that is a good third variant!

 

An interesting example of "plane through three points" which I have not used before.

Project > Intersect, requires the selection to touch or penetrate the sketch plane.

 

Might help...
