I designed a great ball storage that is articulated and is perfectly functional. The great ball opens by pressing the button in the middle and is operated by a simple elastic band. The assembly is done by snap-type mountings, and does not require adhesives. A simple piece of filament is used as a hinge.

Components:

• Inner great ball parts

• Exterior inserts(must be printed in 2 colors)

• Lock mechanism(base, hook and button)

• Stand

• Rubber band 60mm

• Filament hinges
