An elegant, soaring phoenix seems to leap off the surface, complemented by the unique sense of negative space characteristic of traditional Chinese painting—simple yet sophisticated. Based on this concept, we’ve created a set of pen holders with a regular octagonal cross-section, available in three sizes.

The large size has a diagonal outer dimension of 96 mm and a height of 120 mm.
The medium size has a diagonal outer dimension of 80 mm and a height of 100 mm.
The small size has a diagonal outer dimension of 64 mm and a height of 80 mm.

Please note that manual measurements may have slight deviations; the actual dimensions shall prevail.
 

The small and medium sizes can be used as standard pen holders, while the large size is versatile: it can serve as a pen holder, a chopstick holder, or even a container for knives and forks—combining aesthetic appeal with practical functionality.

After numerous printing tests, we’ve found that 60 mm/s is an optimal print speed for silk-like filaments. Printing too fast can cause the model to lose its silky sheen, whereas printing too slowly consumes excessive time, making the trade-off unfavorable. If you’re printing non-silk filaments, you can download the file and adjust the print speed accordingly before printing.
 

Another important consideration when using the octagonal spiral infill pattern is that, due to the frequent turns, the flow rate should be reduced to 0.95–0.97; otherwise, the surface will become extremely uneven. This is especially true when using multi-color filaments: reducing the flow rate while printing with the octagonal spiral results in a strikingly textured bottom and top surface.

We plan to release more fun, engaging, and practical designs in the future.
We hope you’ll enjoy them—your support is the greatest motivation for me to keep creating.
