How about trying a bit of Araldite on an inconspicuous part of the case and see if it truly adheres or just forms an apparent bond which can be lifted off with little effort?
If you want glue suitable for ABS ask a shop which has components for plastic aircraft models. Maybe something like "Plastruct Plastic Weld" which claims to be a general purpose plastic solvent cement for bonding Plastruct ABS etc.
Great idea. Will try that.
I actually found some Plastic glue in the garage that I will try, but I also picked up some of the Super Strength Araldite to give it a whirl as well. Hopefully I can find something that works.
It's unlikely to bond plastic to metal though, is it?
