Cardboard Roll Insert

I created this quick, functional print to make cardboard filament spools roll easier while hanging on the machine. It's nothing difficult, but figured I'd share because it might help out someone else. Happy Printing. Note: I've discovered that some spools are slightly wider than others (Elegoo for instance). For these wider spools I tweaked the scaling in my slicer to make the Z distance 66mm or 106%, but make sure to leave the X&Y scaling the same (100%). 

Also, if you make this design, PLEASE like and add a make. It helps makers/designers earn points! I appreciate it. If you have any questions or concerns, just let me know! THANKS
