My campervan uses mainly the type of lock from the picture. To lock a door you need to press the button. I regularily forget to lock the kitchen drawer and it moves while driving. I wanted something that locks automatically but couldn't find a commercial part that could directly replace the original lock.
This thing is similar to other locks I found. It needs a metal grip at the outside to protect the lever. The parts are connected with M3 screws of varying length. You also need a small spring. I printed the grip in wood PLA but it doesn't really look well. I need to get some silver PLA.
The part 26 is a very direct replacement for the lock. I wanted to use it for another place, but the mounting did differ there. So I made part 28 which has the locking part 5mm higher and 2mm nearer to the front side. I made 2 "Hebel2" to get the right distance, but I don't remember which one I finally used.
Some holes need a thread to hold the screws. Some might need a drill to get the correct diameter.
