I used the clip on the side filament clips but when I was stacking the rolls, the clips always popped off and my filament uncoiled. I designed this to be super easy to use, super easy to print. A set and forget helping hand. I print these when I am coming to the end of a roll or as a purge item so use it up with something I can always use. Once it is attached, you can pull it through to snug it up if you like!  

Pro Tip :) To get it onto the filament that is on the roll, I loosen up a little so there is some slack to click it on.

No supports needed.

This was printed with Black and Yellow Bambu PETG
 

Click the Thumbs up !!  

Thank you for looking and I hope this helps you i your printing adventures :)
