This Mars base–inspired piggy bank turns saving coins into a small futuristic display piece. The structure resembles a compact planetary outpost, complete with a faceted dome roof and modular base walls. Coins drop through the slot on top and collect inside the chamber, while the wide footprint keeps the bank stable on a desk or shelf.

The design draws inspiration from the idea of a small research base sitting on the surface of Mars. The geometric dome and structured walls give it a sci-fi architectural feel, making it look more like a miniature habitat than a traditional coin bank. A removable cork at the base allows you to empty it easily, so it can be reused again and again without breaking anything open.

This design is also part of a personal challenge I’m doing for the year 2026: designing and releasing a brand new 3D printable model every single day for an entire year. Each design will explore a different idea—some practical, some playful, some reflective. If you enjoy following creative processes, testing new designs, or simply watching ideas turn into physical objects, feel free to follow along and join me on this 365-day journey.
