I'm using it for all my Polymaker cardbard spools. They have the problem to rub inside the AMS lid when completely closed but I tried thinner models and these smaller ones break easily. I'm using them every day and I'm satisfied.
Very useful for all my Polymaker spools. couldn't find a PETG profile so I made one. Check out some of my models. I think you will like my 1KG spool holder. it works with your Polymaker remix.
