📏 Model Specifications

• Model Type: Filament Spool Holder Reducer / Adapter
• External Diameter: 75.1 mm
• Compatibility: Elegoo CC and compatible Filament Spool Professional Lab setups
• Design: Cylindrical reducer with retaining flange
• Function: Spool centering and fit adjustment
• Recommended Material: PLA or PETG
• Printing Method: FDM / FFF 3D printing

Important: Please measure your filament spool's center opening before printing to confirm compatibility with the 75.1 mm external diameter. Fit may vary depending on printer calibration and spool manufacturing tolerances.

🖨️ Recommended 3D Printing Settings

For a strong and reliable adapter, I recommend:

• Material: PLA, PLA+, or PETG
• Layer Height: 0.20 mm
• Infill: 20–30%
• Wall Loops: 3–4
• Top/Bottom Layers: 4–5
• Print Speed: Moderate
• Supports: Check your slicer preview and print orientation
• Brim: Optional, depending on bed adhesion

PETG can be a good choice for additional toughness, while PLA is suitable for many normal indoor printing environments.

🔧 Why Use a Spool Reducer Adapter?

Some filament spools have larger center openings that may not fit securely on certain spool holders.

This can result in excessive movement, poor centering, or inconsistent spool rotation.

This adapter is intended to help by:

• Reducing the gap between the spool and holder.
• Improving spool alignment.
• Providing a more stable mounting position.
• Making compatible filament spools easier to use.
• Offering a simple, reusable solution without modifying your original equipment.

Actual performance depends on the spool, holder dimensions, and installation.

❤️ The Idea Behind This Design

As someone who enjoys 3D printing, I know how important it is to have a practical and well-organized printing setup.

I created this Spool Holder Reducer Adapter to solve a simple but common problem: filament spools with larger center openings that don't fit as neatly as they should on certain spool holders.

Instead of replacing the spool holder or using temporary solutions, I wanted to design something simple, functional, and easy to 3D print.

The result is this 75.1 mm Spool Reducer Adapter, a small accessory that can make filament spool mounting more convenient.

Sometimes the simplest 3D printed solutions are the most useful! 🖨️

🎯 Perfect For

• Elegoo CC users with compatible spool holders
