This was a quick idea I had, to enable myself to hang my swiffer on the side of my fridge since there is some space to hide it there.

The design should be printed with more shells than normal to help ensure rigidity. There are cutouts on the bottom for 42mm x 20mm magnets, which is how the print secures to the fridge. Make sure to buy strong magnets if you’re going to attempt this yourself 🙂
