The designer's attention to detail shines through in every single part.
The components used, including the base, shaft, candle workpiece, and gears, come in a variety of colors and shapes. They are all ingeniously designed to be 3D printed without the need for support structures. You can truly feel the dedication poured into balancing the aesthetic beauty of single-color molding with the ease of assembly.

Watching the piece take shape skillfully while using adhesive is incredibly satisfying.

The finished keychain is more than just a decoration. When you turn the handle, it functions as a authentic mechanism where power is transmitted through the gears to rotate the workpiece. Created with the image of children playing with it in mind, Tsunezou-san shows it in action at the end.
