Camper / caravan mosquito net door latch

thingiverse

Humans have created three different door lock mosquito net designs for campers. The first version, shown in a photo, requires two washers and one screw to assemble. To secure the positions, one washer must be slightly bent. The second design also needs two washers, an M3 nut, and an M3 screw to complete. The third version is made using 3D printing technology and requires two washers, an M3 nut, and an M3 screw that measures between 20-25 centimeters in length.
