Parametric Ripple Pen Holder

The inspiration for this pen holder comes from the classic Lissajous curve. By superimposing the trajectories of the parametric equations x = sin(3θ) and y = cos(5θ), rhythmic periodic undulating patterns are formed on the surface of the cylinder. When light passes by, the fine ridges create flowing moire patterns of light and shadow, as if the rhythm of mathematics has been frozen at the fingertips.

🛠️ print parameters

🎨 Product highlights

- Precision texture: Each edge line has been parametrically optimized, providing a smooth touch and visually presenting a sense of high-end precision CNC engraving.

- Light and Shadow Magic: Light from different angles will create changing bright and dark stripes on the surface, giving the static pen holder a dynamic visual effect.

- Practical Aesthetics: The top edge is smooth and the bottom is stable and anti-slip. It is not only a practical tool for storing stationery but also a desktop decoration that showcases taste.

这款笔筒的灵感来源于经典的李萨如曲线，通过参数方程  x = sin(3θ), y = cos(5θ)  的轨迹叠加，在圆柱体表面形成了富有韵律的周期性波动纹路。当光线掠过，细密的棱线会产生流动的摩尔纹光影，仿佛将数学的韵律凝固在了指尖。
- 精密质感：每一条棱线都经过参数化优化，触感顺滑，视觉上呈现出精密数控雕刻的高级感。

- 光影魔术：不同角度的光线会在表面形成变幻的明暗条纹，让静态的笔筒拥有动态的视觉效果。

- 实用美学：顶部边缘平滑，底部稳固防滑，既是收纳文具的实用工具，也是彰显品味的桌面摆件。
