A seesaw duck on a spring that gives you memories of the good old days in a playground! (hopefully only good memories XD )
you can print it with a layer height of 0.2 or 0.3 you probably need some supports for the duck's mouth. Infill 10% - 15%
build instructions:
Glue the spring in the hole at the bottom of the duck then in the base. Don’t forget to glue the handle in the duck‘s head.
