Summary

This fridge lock is a remake of "padlock hinged hasp - two sizes by Tokrmaker" adjusted with a small clip to pop in the 'staple' and attached to the hasp so it doesn't get lost. This object was made in Tinkercad. Edit it online https://www.tinkercad.com/things/9sk9wKY8IUt
I stuck it to the fridge with 'nano-tape' a kind of goey ribbon that sticks things to things without adhesive. It can be removed without damaging the surface.
