Out of a sudden whim, I created this set of lucky mahjong keychains, each embodying a heartfelt wish: “Prosperity at Every Turn,” “Success in One Shot,” “Profit Beyond Measure,” “Unify the World,” and “Make a Stunning Impression.”

The models were printed using a layered approach, which helps conserve materials—and thanks to the ability to pause and manually swap filaments, even printers without multi‑color capabilities can produce these pieces. Currently, the design is configured with five distinct colors.
