DJI Air Unit O4 Pro - Spacer & Damper (2.5mm)

### 💡 The Problem: Lack of space, vibrations, or heat buildup at the Air Unit.

When building a compact FPV drone, sometimes you need just a few millimeters of extra space for cabling. At the same time, isolating the sensitive Air Unit from frame vibrations is crucial for clean video, and ensuring adequate cooling is a must.

This small but effective part is a multi-tool that solves all three problems at once.

### The Solution in Detail:

* ✅ **Dual Function: Spacer & Damper:** Printed in a rigid material like PETG, it serves as a precise 2.5mm spacer. Printed in flexible TPU, it becomes an effective damper that isolates the Air Unit from high-frequency vibrations from the frame.
* ✅ **Integrated Cooling:** 1mm deep ventilation slots are integrated into the design. These create an air gap that allows heat to dissipate from the top of the Air Unit, even when another component is mounted directly above it.
* ✅ **Precise Fit:** The spacer is designed to fit perfectly on the inner 20x20mm mounting pattern of the DJI Air Unit O4 Pro.

### ⭐ Optimized 3MF Project File

You'll receive an optimized .3mf project file that can be loaded directly into Bambu Studio (and other compatible slicers). The model is already optimally oriented on the build plate for a perfect print. No guesswork – just load and print!

All our designs are tested on a Bambu Lab X1C to ensure high accuracy and functionality.

### 🔧 Recommended Print Settings

* **Material:** The choice depends on the desired function:
   * For use as a **Spacer**: **PETG, ASA, or ABS** are recommended.
   * For use as a **Damper**: **TPU** is required.
* **Wall Lines (Walls):** 2
* **Infill Density (Infill):** 25%
* **Infill Pattern (Infill Pattern):** Gyroid
* **Supports:** Not required.
