This spool holder is designed for cardboard spools and helps improve spool handling during printing.
The design reduces direct wear on the cardboard edges, preventing cardboard dust and debris from falling into moving printer components such as belts and rollers.

Features:

• Smooth and stable spool rotation
• Reduces cardboard abrasion and dust buildup
• Helps protect belts and moving parts from debris
• Easy and fast installation
• Compact and lightweight
• Simple print without supports

Instructions:

1. Print the model.
2. Attach the holder/adapter to the cardboard spool.
3. Ensure proper fit before use.

Considerations:

• Recommended materials: PLA or PETG
• Cardboard spools may slightly change dimensions depending on the printer.
• If the fit is too tight, try to use one of the other dimensions.

This model is especially useful for reducing cardboard particles inside enclosed feeding systems and improving long-term reliability during printing.
