The catch on my daughter's lunch box broke off. She liked her lunch box so I printed a replacement catch.

One end has an indent to help fit it on the protrusions of the lunch box. Make sure you fit it the right way around (see photos).

I printed in PLA without supports and 15% infill. Yet to see how it is for longevity.

UPDATE: yeah don't use regular PLA. It won't like it when someone forgets the lunchbox is no longer dishwasher safe. Good until then.

Turns out you can actually buy spare parts! I might have saved some time if I had looked but its so rare companies provide such services I don't often think about it - this is what happens when you own a 3D printer...
