Hand Water Pump

thingiverse

Old-style hand pump, crafted to fit seamlessly onto a large water bottle, effortlessly works anywhere without limitations. To begin using this versatile pump, please follow the simple instructions. To start, find two marbles or balls that can be used to seal the hole; both need to be over 8mm in diameter for optimal performance. One marble can be as large as one inch, though smaller ones work even better. You will also need two #17 Oring rubber gaskets available at your local hardware store (like Home Depot). To get started, find two marbles or balls that fit perfectly inside the hole of a large water bottle, then simply drop them in and seal with a 1/2IN ID hose attachment to prime the pump for easy use. The length of hose required depends on how well you are able to create a tight seal, making each pump truly unique. With the Oring part included, the process is quite straightforward - simply snap it into place like a jigsaw puzzle and you're good to go! Alternatively, if you have access to 3D printing, consider creating your own rubber gasket. Don't forget that a simple hose siphon works just as effectively, so experiment and see which method suits your needs best.
