This mechanical digital clock is both mesmerizing and confusing

Smartwatches and digital clocks can offer all kinds of features, but their customization options are practically limited to changing watch faces. In contrast, analog and mechanical clocks offer more possibilities and variety in design, making the space a lot more interesting. Not just the high-end masterpieces of art, of course, but even the rather unusual and mind-boggling design explorations made possible by 3D printing and consumer electronics.

The Triaxial Numechron Clock brings a fresh twist to DIY timekeeping projects with its unique mechanical design. This homemade timepiece features three wheels with 3D printed digits positioned along different axes – X, Y, and Z – creating an eye-catching display that’s both functional and visually interesting. As the wheels rotate and intersect, they create a fascinating mechanical movement that makes checking the time much more entertaining than glancing at a standard digital clock face.

Unlike most digital clocks that rely solely on electronics and displays, this project achieves its numerical display through 3D printed parts and basic mechanical principles. The digits rotate into view with each passing minute, driven by simple gearing mechanisms that makers can build themselves. The project strikes a nice balance between complexity and accessibility, making it an appealing weekend build for anyone who enjoys mechanical projects or unusual timepieces.

The entire clock runs on a single stepper motor, which keeps the design relatively straightforward despite its complex appearance. This motor drives the gear system that coordinates the movement of all three digit wheels. The design demonstrates how clever mechanical thinking can create impressive results without requiring expensive components or complicated electronics, making it accessible to hobbyists working with basic tools and materials.

All parts of the Triaxial Numechron fit within a 180 x 180mm area, making it compatible with most standard 3D printers ensuring that makers don’t need specialized equipment to produce the components. The files are readily available online, and with some patience and attention to detail, anyone with a decent 3D printer can create all the necessary parts for this unique timepiece.

The clock features practical manual time adjustment, allowing for easy setting without fiddling with programming or electronics. It adds another layer of charm in addition to the mechanical nature of the whole contraption. Simply adjusting the position of the wheels lets you quickly set the correct time whenever needed, giving the owner direct agency and a feeling of control, probably even more than the mysterious black boxes that are mechanical watches.

For makers and tinkerers, the Triaxial Numechron represents an enjoyable project that combines several interesting elements. The build process involves 3D printing, basic mechanical assembly, and a touch of electronics for the stepper motor control. The finished clock rewards builders with both a useful timepiece and a fascinating mechanical display that showcases the maker’s handiwork and attention to detail.
