John, I have used JB-weld to rebuild plastic parts (commercially manufactured) so that I could drill and tap where a threaded support had pulled out. I just used clay to build a dam around the area that I wanted to fill with epoxy. Then after setting I drilled and tapped the new support. It was much stronger than the original part.
