Just tested this on my OpenTag3D tags and it can read and write them as-is, including the goofy non-genuine bootleg tags that other apps struggle with. Works great!

Super easy to use; great for managing filament RFID tags, I use it for my Snapmaker U1 running Paxx12 firmware and it’s indispensable

Awesome app for use with tags that work with the Snapmaker u1 extended firmware.

Thank you—the printer was the reason I developed the app.
- Added support for OpenTag3D (V2).
- Added the ability to search for filament colors by hex code in the filament list.
- Improved TD1 handling with direct access to search in the new filament list.
