IDEA BEHIND THE DESIGN
I kind of anticipated that various 3d model sites will have the usual yearly Christmas design contests. Despite knowing this, I didn't have any idea or concept that I feel is worthy of submission. I wanted something unique, a project that would challenge my skills and stand out as a one-of-a-kind 3D-printed masterpiece.

December came and still, I had no solid idea in mind. Until a video got into my YouTube feed showing a set of green-colored planetary gears. Immediately, I thought, how can I use this mechanism to create a Christmas décor with moving elements that capture the essence of a cozy, festive setting? A scene where people gathered, relaxed, and basked in the warm, lighted ambiance of the holiday.

Now having an idea in mind, I searched for information to help me confirm the feasibility of such project. While I did see fully functioning out-of-the-box animated Christmas villages available for purchase, I have not had one in the past and didn't know how the internals work. Nonetheless, I was convinced that planetary gears held untapped potential for this application.

One of my primary objectives was to create moving elements that evoked genuine winter activities, such as ice skating, rather than static figures merely spinning in place. I think I achieved this through the poses and realistic movements of the skating and dancing figures in the model. And of course the scene would not be complete without a moving train!

To elevate the piece further, I wanted to add light and music, hence the integration of LED strips and an MP3 decoder module, adding an enchanting sensory dimension to the final model. All with the goal of minimizing soldering as much as possible so that more people can do this project on their own.

Another crucial aspect of the project was ensuring that the model could be printed using smaller printers like the A1 Mini. This required careful planning to determine the layout, where to make the cuts, and how to maximize the limited space available for additional elements.

The result is an animated winter wonderland that began as a proof-of-concept. It not only demonstrated the potential of creating animated décor using planetary gears but also served as a personal challenge to push my boundaries and achieve something entirely new and unique 3d-printed piece. I am proud to say that I accomplished my goals for this project.

I hope you find as much joy in experiencing this creation as I did in designing it!
