Spider Web Reusable Spool

This reusable spool's inner hub is 76mm in diameter. The traditional reusable spools are 81mm in diameter. The standard spool of 3D filament hub is approximately 88mm in diameter. All was well until the one day I received a spool where it's inner hub was slightly bigger than only 76mm in diameter. As you can tell a 76mm diameter spool will not fit on an 81 mm diameter hub. So none of my reusable spools would fit. The ones I've downloaded and printed (honeycomb pattern) and one that I bought from an online 3D printing Enterprise.So I downloaded another one based on the filament's manufacture. That was a big mistake! The hub was even bigger than the standard 81 mm hub. For this reason I will not name the filament's manufacture as that is misleading and probably fluctuates in their spools of 3D filament. So after being burnt on that and unable to trust other peoples designs with misleading filament manufactures I decided to design my own with a spider web look. Actuall
