Hi Cameron:
You may wish to attempt to weld it. I have done plastic welding with a hot air gun with a filler rod. I have also done plastic welding with a hot iron and filler rod. Both methods workded very well!
After welding, one may dress the weld to fit or to just look nice. Of course your filler should be the same type of material as the base material. Some times one may take material from a part of the device that does not need it.
The idea of placing small pins or screws prior to welding may be very helpful.
Good luck,
Franchi
