Working Thirst Zapper

This model is just a shell for the mechanics of a cheap water gun.
If you are looking to have a static model that is closer to the actual gun from the game I would recommend using my other design.

You can use pretty much any cheap gun to get the mechanic from (pictured above), ei: https://www.amazon.com/Rhode-Island-Novelty-Water-Pistols/dp/B002JVIFXW/

The cap may need to be printed at 100%-95% the size (don't alter the height) to get it to fit well (i used 97%)

This prop requires alot of post processing as well, filling in the all air gaps takes a while.
