This water gun is easy to assemble and print

This does not require glue, but depending on the condition of your 3D printer, you may need glue.

How to assemble?

The largest of the printed objects will be the body. There is a groove in the body, and before inserting the parts that fit into the groove, a long, mushroom-shaped stick is inserted. After inserting it into the groove, the remaining objects are inserted into the poles that protrude from the body.
