Female USB cover

This thing is a cover for USB ports. You can use it anywhere where an unused female port may collect dirt or liquids. This gadget is not water tight but its better that letting the port uncovered.
It design is very simple and wastes no material. I needed it for my computer because the ports are on top of the case and since the area is always dirty I do not want that dirt in contact with my ports. The material used was white PLA. You can use any other color if you want.
