I can't remember who reminded me of this process about a year ago but I just used it to repair a broken hinge on my 19 RTL.
You will need a small bottle, some acetone and a black ABS fitting from the hardware store.
I used a drill then snips to create small pieces of ABS. Put the pieces in the bottle and add some acetone. It will take a few hours but you are making your own glue. Adjust it until you have a thick mixture.
I removed the complete lid and hinges. One side at the point where the hinge attaches was broken away and a section was missing, the other side was broken but still matched up. The top part was intact but weakened.
Use a q tip, rag, brush etc with some of the acetone to clean the area well. Cleaner the better.
Start by forcing any split parts apart and using something like a popsicle stick coat it with your glue so it gets into the split. You can replace any missing sections you encounter with the glue.
I like the popsicle sticks for the tool. You can cut them into a few different shape before you start so you can form just about any shape.
The glue needs to be thick, but not as thick as putty, you want to be able to work it into tight places, but you want it to stay put and not run after placement.
Let it dry for 24 hours and it is once again one part.
That said, I am on the lookout for some 1/2" wide thin but strong steel stock. I intend to make the center section slightly wider than the hinge itself then right angles up to the face of the exterior of the case then bend over about 1/2". Naturally I will drill 2 holes for the hinge but on the outer part that will rest on the face of the case I think I will drill a few small holes and then use the ABS mixture behind it getting forced into the holes as I screw everything together. Hope that's clearer than mud
