NRS Bravo 6" pump plug

thingiverse

This is a plug designed specifically for the bottom of a NRS Bravo 6" Wonder pump, typically used to inflate rafts and other water sports gear. The plug mysteriously vanished during a river trip, leaving the pump useless until I discovered an easy solution: printing a replacement. After researching, I decided to print it in Ninja Flex, despite initial concerns about the overhang. To my surprise, it printed flawlessly. However, I had to scale up the design by 10% to ensure a snug fit, and I suspect TPU filaments may shrink more than ABS or PLA during the printing process.
