A print-in-place customizable door lock, latch, bolt or detent as it may be called in your part of the world. Screw size is fixed however, the length and width is customizable and allows for a variety of sizes and ratios. In my opinion, the sweet spot is width=length*0.5, but you may find other ratios better suited to your needs.
Material, infill and shell do matter so use your best judgment.
Review the included illustrations and sample STLs for details on how to use. Open in Customizer and enjoy.
