The BinaryBin is a fully 3D-printable, snap-together locking container powered by a programmable 16-bit binary code. It’s part puzzle, part teaching tool, and 100% nerdy—in the best possible way.
**What Makes It Special:**

- Mechanical DIP-style binary switches (16 total) grouped into 4 nibbles for easy binary → hex conversion
- Orbital gear-driven lock system that only disengages when the correct code is entered
- Programmable mechanism lets you set your own combination
- Non-binary switch state lets you “erase” the visible code after unlocking
- Hexadecimal encoding legend built into the layout (great for teaching or learning)
- Concealed mechanical latches, controlled entirely by the geartrain
- Fully printable — no electronics, no glue, no screws

**Educational & Fun**
Learn (or teach) how binary and hexadecimal systems work—by actually using them. It’s a brainy hands-on demo disguised as a seriously cool lockbox.

**Ideal For:**

- Puzzle lovers & escape room designers
- STEM educators & students
- Nerdy gift-givers
- Makers and collectors of mechanical marvels

**Printing Tips:**
- No supports required – all necessary supports are built in
- Includes an optional tool for disassembly
- PLA recommended with standard 0.4mm nozzle
- Full print & slicer settings included in the images

**Code it. Turn it. Unlock it.** The BinaryBin isn’t just a container—it’s a hands-on lesson in binary logic, gears, and clever design. Post your prints, remix your codes, and share your builds!
