This is a 45°-inclined base model designed specifically for 92mm (92x92x25mm) fans, intended to repurpose idle computer cooling fans into stable desktop fans or auxiliary solder‑suction/exhaust tools. The design was inspired by the need in DIY projects for gently directed airflow at a precise angle, as well as by the desire to mount standard‑screw‑hole fans more neatly and securely on a desk. For printing, PLA or PETG is recommended; the model features a compact structure and typically requires no supports throughout the print process.
