This is a hollow storage cylinder that combines practicality with decorative appeal, suitable as a pen holder, a small vase, or a desktop organizer. Its design draws inspiration from the delicate elegance of lace trim, transforming traditional textile patterns into three-dimensional geometric structures and imbuing everyday objects with an artistic flair.

The openwork pattern at the top is a suspended structure that requires tree‑like supports (with a recommended support density of 15%–20%) to prevent sagging or deformation during printing. For fine details, a layer height of 0.1 mm is advised to ensure crisp lines. PLA is recommended for its ease of printing and excellent detail reproduction; if the piece will hold water long-term (e.g., as a vase), PETG is a better choice due to its superior moisture resistance.
