/diy/ - Do It Yourself

Can't afford a chamfer in the inside there to make it an easy print?

I'd do separate supports.
Design a grid/lattice that will fit into the opening, just a big square like what I assume would eventually be inserted in there.
Print it separately.
Do this print, add a pause before it begins that overhang, insert your separately made support.
Bonus points, you can make it out of PETG and PLA won't stick to it worth a damn, nice trick.

It's a neat trick, not as versatile as it might seem off hand, but it's perfect for situations like yours here.
