When I first started printing, I noticed that there was a lot of free movement from the spool on the holder. Being very new to printing, (I am still very new) I wanted to design something as I still didn't know how to use pages like Printables. So I set out on a journey, a oh so long journey…

Just a very simplistic design to help with the spool wobble. If fits most spools of the 1KG size. Plastic and Cardboard alike. Simple solution to a simple problem.
