Watertight Mask Container using Soda Bottle Caps (PCO1810)

thingiverse

It is time for kids to go back to school, and they need masks. This is a mask container that was remixed from my design of containers/round boxes reusing soda bottle caps. I thickened the bottom of the container and added a U-shaped tunnel, as shown in one of the cut-out diagrams. We can pass through some string or thread or even zip-tie and hang the mask container to the backpack, or even a lanyard. It is always a good idea to have a spare mask handy during this pandemic time. The container needs a screw cap. It is designed to work with a PCO1810 standard screw cap, for example, the caps of Pepsi or Coke bottles.
