4040 Desktop Mini Fan

Source of Inspiration: Addressing the need for localized cooling on a desktop, this design leverages the flexible, bendable nature of stainless steel corrugated tubing to create a compact desktop fan with freely adjustable angles, overcoming the limitations of conventional fans that offer restricted angle adjustments.


Structural Design: The fan body is compatible with 4040‑size cooling fans, while the base features a 3D‑printed circular platform. A flexible stainless steel corrugated tube connects the base to the fan housing; this tube can be bent into any shape yet retains its form, enabling multi‑angle positioning—up/down and left/right. The housing includes pre‑drilled screw holes to secure the 4040 fan.


- Functional Features: Users can freely adjust the airflow direction to provide targeted cooling in specific areas of the desk. Compact in size and space‑saving, it’s ideal for workstation or computer‑side localized cooling. Powered via USB, this makes it a practical DIY science‑and‑technology creation.
