The sandpit bucket consists of two printed parts, the container and the carrying handle. The ear is attached to the container with 2 M3×8 screws and two M3 nuts on the ear, and places are designed in the container for the correct mounting of the screw and nuts. I recommend securing the screw in the nut with a drop of glue so that it does not come loose when the ear moves.
