The honeycomb pen holder is a practical 3D-printed model designed specifically for desktop organization. Its overall structure features a hexagonal honeycomb lattice with hollow spaces, paired with a hexagonal columnar form. This design not only retains the lightweight and high structural strength characteristics of the honeycomb structure but also delivers excellent ventilation and heat dissipation, preventing pens from becoming damp or overheated. The two-color layered design (green + blue) enhances visual depth while making it easy to distinguish between print batches or customize color schemes. The model requires no additional glue for assembly—it is produced in one piece—and is compatible with most FDM 3D printers. It is easy to print, uses minimal filament, and combines industrial aesthetics with practical functionality, making it an ideal desktop accessory.
