If it's an older unit, disassembling is very doable and you can probably just get a little hemicircular tube of metal of the right dimensions and then run with that.

Make sure to unplug it first, of course.

If it's a newer model shit might get complicated because there may be a PCB nearby and it is more likely to have berm assembled with uncmon screw heads (torx or something) or snap-on plastics.

I'm surprised there's no brand! I'd expect to find a sticker or something in the bottom or by the power cord.
