FlashForge AD5X 43mm Spool Holder Adapter – Fix Small Spools Not Fitting

Fix for Small Spools Not Fitting on the FlashForge AD5X

This adapter is designed to solve a common issue with the FlashForge AD5X: many 43mm inner diameter spools don’t fit properly on the factory spool holder.

This model allows smaller spools to mount securely and rotate smoothly, preventing feeding issues and improving print reliability.

✅ What it does

- Adapts the stock AD5X spool holder for 43mm inner diameter spools

- Ensures a stable, centered fit

🔧 Why you might need this

If your spool:

- Won’t fit onto the stock holder

This adapter fixes that issue quickly with a simple print.

⚙ Print Settings (recommended)

- Layer height: 0.2mm

- Infill: 15–25%

- Supports: May be needed depending on print orientation. I recommend printing on the end so the number is facing up. This gives it the most strength.

- Material: PLA / PETG

📦 Notes

- Designed specifically for the FlashForge AD5X

- Optimized for standard 43mm spool inner diameters

- Snug fit—no additional hardware required
