65 cm Bladeless Fan (Dyson-Style)

📄 Description 65 cm Bladeless Fan (Dyson-Style) A functional and stylish bladeless fan inspired by Dyson’s design. The full structure stands 65 cm tall and uses a standard 120 mm computer fan. It's powered via a DC jack cable inside a rubber housing with a built-in ARK terminal, making the wiring clean and simple. The upper airflow ring is made of four parts and forms a continuous air duct with a smooth, modern appearance. 🔧 Key Features: total height: 65 cm uses a standard 120x120 mm PC fan power input via DC jack in rubber housing with a 2-pin ARK terminal clean, minimalist design inspired by Dyson smooth airflow ring outlet — creates a focused stream with slight Venturi effect and mild air entrainment 🛠 Assembly: the 120 mm fan is mounted to the base using M5 screws the upper ring consists of 4 interlocking parts, glued with superglue (cyanoacrylate) once assembled, the upper ring press-fits into the base — no additional screws required the base is designed for a pre-made DC cable with rubber housing and 2-pin ARK connector 🖨 3D Printing: recommended materials: PETG or ASA (better heat resistance than PLA) layer height: 0.2 mm infill: 20–30% supports: may be required depending on orientation, especially for the ring parts ⚠ Notes and context: This is a visual concept inspired by bladeless fan aesthetics — not meant to replicate Dyson’s airflow technology or its efficiency. Unlike the original Dyson design, in this model the air is pushed through a slit on the front edge of the ring, not through its interior. The air stream moves forward , not along the inner ring surface. Still, this directional flow creates a low-pressure zone in front of the ring , which draws surrounding air through the center — similar to the Coandă effect or entrainment seen in fluid dynamics. So even though the internal geometry is simplified, the ring still shapes the airflow and pulls in ambient air through the center. You can observe this effect using incense smoke or a light ribbon — they get pulled forward. 🔬 Further development: Initial tests showed that the fan itself plays a far greater role than the ring shape. Some fans generate heavy turbulence and noise, while others are quieter and much more efficient. I’m currently waiting on several new fan types to identify which design aspects make the most difference. To better understand airflow behavior, I’ve also started experimenting with fluorescent aerosol and UV light , which helps to visually trace the streamlines and turbulence zones. The upcoming V2 version may end up looking completely different — based on these insights and airflow tests. 🙏 Thank you! Huge thanks to the Printables community for all the feedback in comments and private messages — it’s already helping shape the next version of this project. This model should be seen more as a fun experiment or decorative gadget than a serious appliance. Let’s not take it too seriously — the project wasn’t meant to be that serious either 😉
