Rounding/blunting the corner of a cube?

[will.dameron]

Alright, I know this is a dumb question. I have a design for a 3d printed custom tool holder, to go on a tool belt. I have applied fillets to all the edges which makes them 'friendly' enough so that if your arm rubs against them while working it's fine. But, I want the corners to be extra blunt.

So imagine you have a cube - how do you sort of 'push' the corner back so that it's rounded over, like a ball instead of a sharp corner? I know it has to be super simple, but I have not been able to figure it out despite quite a bit of clicking around and searching. Thanks in advance...

You probably want to use the Fillet "Setback" corner type setting.

I did discover that feature, and it almost does what I want, but not quite. The problem is that I have a lot of material to work with on the corners of my model, but very little on some of the faces. So, I have to set my fillet value to pretty small. What I would like is small fillets along the edges, but I have more material to work with on my corners, so I'd like my small fillets to blend into those larger setback type corners... if that's possible. Does anyone know how to achieve that?

Yep, but hats a heck of a lot more complicated than a single fillet feature.

You can adjust dimensions with user parameters in the attached model.

Wow, thanks, at least now I don't feel like it was a dumb question - that was way more involved than I thought it would be.

I was able to follow that workflow and get one corner correct. However, my model is not symetrical at all, and has a bunch of different features. So, splitting the model, deleting one half, and mirroring the first half over doesn't work. To get by I just did the whole workflow over on the other corner. There are two more corners I'd like to do this to, although they're not as important. Is there a way to mirror over the blunted corner feature, but without deleting your model? I tried for a while but wasn't able to get it. No matter what I've achieved most of what I wanted though - thanks!
