Bob-Omb Piggy Bank – with Working Wind-up Key!

Bob-Omb Piggy Bank – with Working Wind-up Key!

Here comes a piggy bank that’s ready to blow your savings away—in the best way! Inspired by the iconic Bob-Omb from the Mario games, this 3D printable model is both fun to look at and super satisfying to use.

Main features:

• Fully functional coin bank: drop your coins through the slot in the back, and retrieve them by unscrewing the fuse-cap on top of Bob-Omb’s head.
• Interactive wind-up key: the rear key actually turns and makes delightful clicking sounds, just like a real wind-up toy! I designed this system myself and I'm especially proud of the satisfying tactile feedback.
• No multi-color system needed: each color prints on a separate plate, making it easy to achieve a multi-colored look without AMS.
• Simple assembly: just a little glue required to bring Bob-Omb to life.
• PLA friendly: prints beautifully with standard PLA.
• Supports required for some parts, but don't worry—they’re already properly included in the print profile I prepared.

This is more than just a piggy bank—it’s also a playful desk toy and a perfect gift for Nintendo fans, gamers, or anyone who appreciates clever design.
