I have a fridge / freezer in the garage, and when the kid slams the fridge door, the freezer door comes open. I found a latch online, but the dimensions did not fit my setup. I made my own, in Fusion 360, fully parameterized version, which is also available for download here.

Key here too is that the flap can dislodge from the lever base. This is intentional, because kids will rip this open without thinking about the latch. So instead of breaking things, it will just come apart, and you can easily put it back on again. I printed mine in PETG for extra flexibility, but any material will likely work fine.

Printing

To print and use this, you have to print one of each 3 parts, The "Fridge Lock Lever" is the same always, but you have to pick a flap and a latch of the appropriate length. If none of the ones I uploaded fits your setup, you can always make your own from the above, or, post a comment and I can add another one meeting the requirements.

This is easy to print, no supports or anything needed, just snap the lever and the flap parts together, and use some strong double sided adhesive tape to mount. 3M double sided tape is great.
