Design Concept
This fin‑repair tool features a clever design that effectively restores the shape and functionality of air‑conditioner fins. Its simple, practical structure allows easy access to reach and straighten bent fins.

Application Description
Specifically designed to repair deformed fins on air conditioners, this tool enhances airflow efficiency and improves overall equipment performance. Whether you’re a professional technician or a DIY enthusiast, this tool helps maintain your air conditioner in optimal working condition.

Printing Recommendations
For printing, we recommend using high‑strength filaments such as PETG or ABS to ensure durability. A infill density of around 30% is suggested. Due to the model’s straightforward design, no support structures are required.

Assembly Instructions
After printing, stack the components and secure them together with pins. However, be sure to thoroughly clean the finished part afterward to remove any print residues that could affect its performance. To use, insert the tool into the fin and move it up and down to realign bent fins. You can adjust the model’s Z‑axis height to match the fin spacing, or gently bend the tool’s blade to fine‑tune the gap for different fin pitches.
