Snowman statue with hidden compartment (18x118mm). Just unscrew the hat! ;)
There're two versions of hat. File "hang_hat" contains model of the hat with hole at the top of the part, so you can piece of string to hang snowman somewhere. File "hat" contains fully-closed hat at the top. Both versions work like screwable lid for the compartment.
Total height: 131mm
5% infil with 2 perimeters will suffice. No support needed ;)
For buttons and eyes take piece of 1.75mm black filament. Heat it on one end and squeeze it flat! Then just glue it on its place.
