I’ve had this part stored in my bedside drawer for years and I can’t remember what it’s for.
My best guess is it’s from an overlocker that I no longer have(?)
SOLVED: It’s a hinge cover for a fridge freezer set that clips together to look like one large machine. Thanks to everyone that contributed.
Because you said “bedside”, I’m going to guess this is part of Window Treatment. Do you have Venitian blinds or roller shades in your bedroom?
