Made some addition for my spool shelf design, filament material tags so you can separate different type of filaments from each other on one shelf and not mixing them accidentaly. Tags are just clip on, no additionl hardware required.
This fits my spool shelf here with all different dimension wooden dowels, 20mm, 23mm and as well 1inch: https://makerworld.com/en/models/88779#profileId-95016
Also added multicolor version.
Added some more tags, now it contain: PLA, ABS, ASA, PETG, NYLON, TPU, CARBON, GLOW, FLEXI, CLEANER, MARBLE, MATTE, SILK.
Also added blank tag so you can add custom text as you want.
If you need tags with different text, just let me know :)
