Haha, that's certainly a good way of making a positive out of a negative with dust magnet toys :)
We repurpose dildos fairly often. One on my partners bedside cabinet is a loo roll holder (for post sex clean up, night time runny noses etc). One on my side is a hair bobble holder. They often act as paper weights on my desk, or to prop up items I am photographing (hidden behind the object obviously). They make good emergency spider killers when a spider infiltrates your bed. The list goes on. They're more useful as objects than as sex toys in this household!
I've briefly used a (retired) suction cup butt plug as a door stop. Effective!
Can't think of anything terribly out there we've done with toys though tbh.
