Universal RFID Swatch for Reuse of Tags (Easy Swapping)

These printable filament swatches combine physical color/material samples with reusable RFID tags to simplify filament management in multicolor printing systems. The design has two parts: an RFID tag enclosure (up to 26 mm in diameter) and a swatch with an 8-step gradient window (0.2 mm per step). The enclosure snaps into the swatch. When filament runs out, the RFID tag can be removed and reused with another swatch, allowing reprogramming and reducing waste. A keychain hole improves organization, and the gradient helps evaluate how different thicknesses interact with light. These are the RFID tags I recommend (don't user the paper ones): https://s.click.aliexpress.com/e/_c4r7ikut If you need Ring Keychain Connectors, you can use these: https://s.click.aliexpress.com/e/_c3kJ2YhL -- Side note: This also includes swatch models for the most common printable materials. There is also a blank text swatch, so you can label the material with a marker to a written sticker. For better quality, follow the file “print orientation.3mf” objects' orientation.
