*New Version V4 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

Design Concept

The design is focused on protecting filament spools using a customizable adapter system that includes a reusable NFC tag feature. The round protectors ensure stability and alignment while in storage or during printing. Photo'd is all the different spools this has been tested on with and without a CFS color change

This design was made as my cardboard spools kept coming bent and then either lost fragments, completely didn't work or just got damaged in the CFS. I wanted to either protect the spools/my CFS but not have another set of spool adapters, so this design was born. This is the 3rd version of a spool adapter and now works on plastic spools which have arrived broken and now includes a Reusable NFC Tag Print and slot.

This design provides has a universal fitting for all spool types that are 203mm in diameter or less and has 4 main functions,

1. Protective barrier for the CFS when using cardboard spools and prevents small debris breaking up and making its way with the filament.

2. Protects the structure of the cardboard spool, prevents wear and extend the lifespan of your spool.

3. 200g or 250g or small spool size adapter to CFS. Fits most spools without need for any extra parts needed to be added and for the others there is 2 cone shaped accessories slid on the protectors.

4. Spare spool. With the large cylinder adapter this will function as any other spool would with a 45mm spool holder capability. The adapter even has a 2mm hole to house the beginning of the filament.

5. NFC programmable tags can be used on the adapters using the print on plate 4. If you are like me you can add text to the tag 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.

Printing Suggestions

Use sturdy materials such as durable PLA or PETG for a strong build. Consider a layer height of 0.2mm to balance print speed and detail. Infill of 20% should suffice for strength without excess weight.

I will include both a PETG and PLA project file, but the PETG is best for the strength.

Assembly Instructions

Ensure the fit is secure on standard spool sizes. The components should interconnect smoothly, and the NFC tag can be lodged into the designed groove for additional functionality. Double-check alignment for continuous cleanliness and order. Make sure you line up the spools so they stand evenly or they will move side to side in the CFS, usually no issue but can be

Improvements from V2 to V3:

- reduced contact surface to aid when in used with damage spools

- Stronger design

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

l-ess sharpe 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

-less need for the spacers when using most smaller spools.

-Outer and inner printed separately so can be printed in different materials, e.g TPU our for grip and PLA inners for speed of printing.

FUZZY SKIN ALERT

On the last design I needed to turn on fuzzy skin when printing to increase grip. This is under others/ special mode/ fuzzy skin. This creates a textured finish and improves grip in the CFS.
