If the broken bit is plastic only, and you've got the parts, and can assemble it like a jigsaw, get some Liquid Polystyrene cement - the runny kind, not the gel stuff.
That'll weld the parts back together like new. It takes a while to set though, so find a way to keep the parts clamped together for 8+ hours.
Do it overnight and it'll be set in the morning. Then it should reassemble like new.
Please take off topic discussion off this forum. Thanks.
