Lifestraw Cap

thingiverse

The owner fashioned a cap for their dad's Life Straw using the threads from the matchstick holder. A Life Straw is a portable water purification device that fits snugly onto a standard soda bottle. It was intriguing that it didn't come with a cover for the open end of the filter when not attached to a soda bottle. The owner cleverly used the threads from the matchstick holder to create a cap that covers the exposed end of the Life Straw, providing ample space for storing an extra gasket.
