Winter Wonderland
A 3D-printed clock with a small winter world hiding inside
A personal Christmas gift that turned into a small design and fabrication experiment: a functional 3D-printed clock built from layered winter scenery, with internal lighting that changes the scene from a clean daytime object into a miniature night-time landscape. I designed both the physical piece and the renders, including a slightly obsessive method for reproducing real print-layer texture digitally.
Brief
I wanted to make a Christmas gift that felt genuinely personal rather than simply decorative.
The idea became a clock with a layered snowy landscape built into its face, combining something useful with a little diorama. It needed to be printable, easy to assemble and visually interesting both with and without the internal light switched on.
Challenge
The physical design had to fit the clock mechanism, multiple printed depth layers and hidden LEDs without becoming bulky.
For the presentation renders, I also wanted the digital version to preserve the very specific surface quality of FDM printing. A perfectly smooth CG material would have looked more 'premium', but less honest to the actual object.
Execution
I designed the landscape as separate depth layers and printed them in white PETG, then assembled the clock mechanism and integrated LEDs at the top to cast controlled light through the scene.
To recreate the printed texture in the renders, I exported the Cura slicing preview and converted the print-head toolpath into bump and normal information. That let the CG model reproduce the same fine ridges visible on the physical print rather than using a generic procedural texture.

Results
The finished piece worked as both a clock and a small illuminated object. In daylight it stayed clean and graphic; with the LEDs on, the same layers became a much deeper winter scene.
The gift was well received, and the project became a useful example of digital design, fabrication and rendering feeding into one another rather than being separate processes.
Personal View
This is the kind of personal project I tend to disappear into: small problem, unnecessary amount of thought, surprisingly satisfying result.
I especially liked using the slicer's own toolpath to reproduce the physical surface digitally. If the limitation is visible anyway, it might as well become part of the design.
