NRS Bravo 6" pump plug

thingiverse

This is a plug that fits the bottom of a NRS Bravo 6" Wonder pump. This pump is commonly used to inflate rafts and other water sports equipment. My plug disappeared one day at the river and the pump stopped working. I was looking into buying a new pump when I realized I could print a replacement plug. I printed it in Ninja Flex and was a bit worried about the overhang, but it printed just fine. I had to print it at 110% in order to get a tight fit. I think the TPU filaments might shrink a bit more than ABS and PLA.
