Note: You need to print two of these to make a complete spool adaptor set.

One for each side of the small spool.

21 October 2025 - Added adaptor sizing / scaling strips (smaller than the ring) to aid in sizing the adaptor to the spool.

You can also scale and size the 100p strip, until it fits your spool, then scale the adaptor to the same % before you print it.

Design concept

The CFS spool adaptor is designed to fit seamlessly with 200 / 250g filament spools, providing a customized and secure holding solution. Its structural design ensures stability and ease of filament feeding, making it ideal for 3D printing enthusiasts who frequently change filament sizes.

Use

Intended to be utilized in conjunction with smaller filament spools, this adaptor enhances the compatibility with various 3D printers, allowing for a versatile and efficient printing setup.

Printing Recommendations

It is advisable to print the spool adaptor with a high infill percentage for maximum durability. Using PLA or PETG is recommended due to their strength properties.

Assembly Instructions

The adaptor fits directly onto (press-fit) the spool holder. No additional tools or adhesives are needed, simplifying the setup process and allowing for immediate use.
