I didn't remove the bulb of tape holding it together.

Epoxy is a mechanical bond. You would want to lay a couple of bridge pins across the joint. Dremel a groove.
CA glue can be amazing on it's adhesion to plastic parts. It looks to be ABS so plumbers pipe glue actually could work. It takes a few coats and then you sand it down.
I have fresh Hot Stuff CA glue. I will give that a try
