SpoolTagWriter

Scan filament NFC tags, browse brand presets, and write spool data with custom colors, materials, and temperature settings from your iPhone.

SpoolTagWriter lets you read and write NFC tags for 3D printer filament spools from your iPhone.

Use it to scan existing spool tags, view the stored filament data, and create new tags with either preset profiles or custom settings. The app is designed to make spool setup faster, cleaner, and easier to manage without digging through raw tag values by hand.

Features:

• Scan compatible NFC filament tags
• View parsed spool data including brand, material, color, diameter, weight, and extruder temperature range
• Inspect raw NFC page data for supported tags
• Write tags using preset filament profiles
• Browse presets by brand, material type, and color
• Create custom spool settings for your own filament
• Choose custom colors visually or by entering a hex value
• Write spool data in a streamlined iPhone-first workflow

SpoolTagWriter is built for makers who want a simple way to manage filament tag data and prepare spools for supported 3D printing workflows.
