Fiberlogy Master Spool Inner Part

I love the Fiberlogy new spool and I use a lot of their refills. But I don't think the inner cardboard part will hold up to wear after repeated use. To prevent any accidents in the future I have designed a replacement to avoid wear and make loading the filament easier.Printing Settings0.2mm layer, 3 perimeters, 15% infill. Orientation should be like this, without any supports. MountingThe two parts should be snap-fit on to original Fiberlogy spool sides. For more secure you can use some superglue.
