We have a Diacro bender, don’t have a 3" radius die but that shouldn’t be hard to make. Might take a few iterations to figure out what radius inner die to use to account for spring back.
One of the mounting feet for the bender was missing and im making a new one, so it only has two mounting feet at the moment. I could meet you sat or sunday afternoon to talk about making a die and how to use it.
