Making a fillet on Inside object

I know you guys know how t do this but , I am having problems figuring out how to add a fillet on the though cuts in this model. Any suggestions?

Thanks in advanced for your time!

maybe Fredo’s round corner tool?
You could also figure it out with the profile you need and use the “follow me” tool?

Fredo’s tools are faster but you should know how to do things manually before resorting to plugins.
This is one manual option.

Thanks for the help!

I never thought to do it that way, but it makes sense. Way easier than what I was trying to do from inside the object.
