I saw the Universal Spool and directly had to print one, even without the need of having one.
Simply the mechanics were too nice, with the snaplock and opening tool.
But the solution of putting the clip simply under a ziptie... well I didn't like that.
So I made this simple hack which makes it possible to attach the lable securely to the Filament.
It is not tested but as far as I see the clearance to the filament should be enough.
If you need different dimensions drop me a line or use the Scad to modify it for yourself.
