Step into medieval times with this fully functional 3D-printed battering ram! This design is inspired by classic siege engines and brings them to life with moving parts and playful details. The wheels actually spin, the main battering ram beam swings back and forth, and the whole model is built to look great on a desk, shelf, or workbench. But this battering ram isn’t just for show. It’s designed as a practical storage solution too — with a clever twist. The model includes two interchangeable versions of the mega beam bottom: Philips OneBlade version – the top section of the mega beam can be removed and used to neatly store a Philips OneBlade.

Universal battery holder version – if you don’t own a Philips OneBlade, the alternative mega beam bottom turns the battering ram into a compact battery dispenser / holder instead.

This way, the model is useful no matter what you have at home — and you can even swap between versions later if your needs change. Finally, even when it’s not being used for storage, this battering ram stands on its own as a fun, medieval-themed desk toy and display piece. The moving wheels and swinging beam make it satisfying to fidget with, and the detailed design makes it a great conversation starter. Once you’re ready, the assembly instructions below will guide you step by step through putting your siege engine together.

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.
