FredoCorner - Ruby Error (also geometry error in other rounding plugins)

Trying to apply rounded corners to this shape:

Tried several rounding plugins - FredoCorner, SCF RoundCorner, etc - they all have issues.

Is there a better method for producing this type of model, with intersecting “sticks” featuring rounded edges?

Maybe there’s a way to create the “sticks” separately with rounded edges, and them merge them together?

Are you trying to round all the edges in one go? How large is the model?

If I were modeling that and wanted the rounded edges I might consider making multiple “stick” objects with the rounded edges and place them as I want. Then use Eneroth Solid Tools or Bool Tools 2 to combine them into a single solid object.

Have you tried Bevel from Mind Sight Studios?
