The arrival of summer and soon my first-born son, I got nostalgic and remembered these water squirting prank rings from my childhood. Now I can relive those happy summer days and so can you!
This is a variation of my print in place Prank Ring with the pump and ring as separate models.

Printing This version has the pump and the ring as separate models so you can print the pump in TPU and the ring with whatever pretty material you want to have it in. Go slow and steady. It's important to get both parts waterproof, otherwise you might end up wetting yourself instead of your target...
There are also different sizes of pumps to choose from for different sized hands.
To assemble, just push the ring into the pump hole.
How to use Submerge the ring in water up until at least the little hole. Squeeze the pump empty and let it suck in enough water. To shoot, simply squeeze the pump. Now go forth and prank!
Let me know if you need a ring size that's not available currently and I'll add it!
