Filament roll roller

thingiverse

This is to help 3d printers like the Ender 3 that have just a tube on top to put the filament roll on. If you get a filament roll that is too big then the printer may have a hard time pulling the filament through because it is harder to spin the roll. My design is very primitive because I am not the best designer but it is mostly just to give you an idea. If you are having this problem then you can use my design or make your own. How this works is it goes into the hole in the filament roll which makes the hole smaller so when you put it on the filament holder it will spin more easier because the hole is smaller. Also, I am aware this is very confusing. Sorry about that but I hope you get the general idea. The dimensions of my design: Outer circle is 73.4mm. The inner circle is 31mm. This will fit my printer but you may need to change it or make your own to fit your printer.
