#Tinkerfun   This object was made in Tinkercad. https://www.tinkercad.com/things/13qDEQ6vFyJ   OK, so I battled this concept in my head for HOURS.  I wanted to make a squirtgun that was TRULY, 100% 3D printable.  Not even so much as an O-ring as a seal or anything!  I didn't even want a single scew or bolt told hold this together.  I thought, "could I make it work, even a little bit?"  I think this will do the trick!  It is by NO means finished.  It looks ugly right now, so I'm working on the aesthetic details now.   This model is made up of 3 pieces: * Tank/resevoir/chamber * Plunger/handle * Lid/guide   The inside of the "tank" is beveled toward the middle, so the water has a better chance of getting into the "chamber".  In order to get liquid into the chamber, you need to pull the plunger/handle back all the way, which will open up an 10mm gap that allows water to enter.  After a second to allow it to fill, push the plunger/handle toward the front, and the plunger will force the water out the nozzle.  The guide on the top of the lid acts to keep the handle/plunger straight, and prevents the user from moving the handle too far and breaking something.   The nozzle is 3mm wide (inner tube diameter), and the tolerance between the plunger and the wall is only 0.4mm.  The front of the plunger is rounded to allow it to find the right path, even if it's a little off center.   I made the walls either 5mm or 3mm thick, depending on what it's purpose was.  The top lid also clips on with little dimples that go in 1.5mm.  Just pull on the tabs on the sides to get the top off (for drying, cleaning, etc).   Remember, don't abuse this.  This isn't the best design, but if used gently, it should function just fine.
