200g or 250g mini spool adapter to 1KG size - Universal- CFS

******NEW VERSION (V4) Here**** 04 02 2026

NFC programmable tags can be used on the adapters. If you are like me you can add text to the tag (10mm height, cut, and 0.4mm depth) to save reprogramming in the future. I will be printing mine in the material used so color matches the programming and the words PLA or PETG etc are on the tag. Featured in the photo/helps my OCD tendencies.

This version is made from less plastic, is stronger, NFC for plastic spools is much smaller and more sensible and the case for the NFC tags works better. Much Much improved lining up of the spool in the adapter compared to V3

- Stronger design

-screw fitting changed to make easier to use and smoother fit

-less sharp edges to catch fingers on when tightening

-NFC tag slot - *Coming Soon - Reusable stand alone attached for plastic spools

-Works with plastic spools if needed

Design Concept

This spool adapter is designed to convert mini spools of 200g or 250g filament into a standard 1KG spool size for more universal compatibility with 3D printers.

Purpose

The adapter is intended for use by 3D enthusiasts who want to use smaller spools of filament with setups that are typically fitted for larger spools, enhancing flexibility and potentially conserving material.

Printing Suggestions

- Print with a strong material such as PETG or ABS to ensure durability, PLA will still do a good job

- Infill density recommendation: 20-30% for optimal balance of strength and material usage.

- Support might not be necessary depending on the orientation.

Assembly Instructions

Simply place the mini spool on top of the adapter. Ensure it is centered and secure the fit to prevent slipping during printing.
