No guarantee anything will stick well, and the more you put in there that less it'll rest on the edge properly. However a bit of super glue and sticking something there probably will work.
My suggestion is leave it alone or print a new one with supports or a different orientation. Bonus points if you print a sliced piece of it first to make sure it prints well. If the waste in filament is expensive, ask for some money to offset. That's the perils of 3d printing and why people charge a couple times filament cost for prints (dealing with issues like this and waste).
