iPhone 4s Captured Gear Case

thingiverse

Revamped iPhone 4s case with rotatable gears now features a tighter rivet fit in version 2. This innovative case incorporates gears that can be turned for endless entertainment. The thumb gear protrudes below the volume buttons, while the ring gear encircles the Apple logo and is held by interlocking tooth patterns of surrounding gears. A large gear at the bottom reveals the iPhone emblem. The design is based on an iPhone 4s slim case blank available at Thingiverse.com/thing:51533. Customization options include adding a name or logo below the large gear. For successful printing, use .20 mm layers for the case and gears with four shells, raftless, and no support; 230/110 temperature and 80/150 speed. Print rivets with similar settings but 10 shells and a 210/110 temperature. Acetone and ABS chunks in an empty nail polish bottle can be used for gluing, although caution is advised due to its flammable and toxic nature. Paint glue on the inside surface of rivets and case with overlap, ensuring snug fit in the case and free movement in gears. Assemble by attaching four small gears surrounding the ring gear first, followed by the ring gear itself and remaining gears. The case is installed by inserting the top of the phone first before snapping the bottom sides around it. For removal, follow reverse procedure.
