Little but useful thing. At least in my case.

Maybe especially useful for those, who respool their filament spools and keep them in reusable vacuum bags. Label is tested on eSUN Spool Vacuum Bags. But this Label Tag can be used in any other case if you have similar bag. Label Clip can be used to seal a bag by sliding through sealer channel.

Tag is made of two parts. Clip and changeable Text Plate.

STL Text plate is clean (I prefer in white colour) so You can use a marker (or add desired text in slicer) and write down your note on it. Or You can use just a simple Paper peace 15x27mm and put it in instead.

For those who can print a multicolor prints and use a Bambu Studio 3mf files, I have done and added here a set of TextPlates with some popular Filament types and brands. So You can use, clone, duplicate the ones you need. If You want do make another text there just take one of presented and edit text you want. 
To do it in Bambu Studio, Just change Global to Objects and edit text of desired object by clicking right mouse button on text line there.

p.s.
Depending on Your Printer Tolerance values You may need to give a little file/sanding to Text Plates sides or just scale them down on Y axis by 0.1-0.2mm with turned off uniform scale.

p.p.s.
If You can't figure out how to change text on Text Plate, you can give me a shout and I will make ones You need.

Oh Yes …. You can Buy me a coffee if You feel good doing so :) (And very big Thank You For interest in my work)
