Reusable spool for Bambu Lab filament

I was looking for a spool for my ever-growing collection of BambuLab filament when I came across push-on spools for Rosa3d filament. Finding it a brilliant idea, I went on to design a version for BambuLab refills, and here it is. Lightweight but strong design using only 64g of filament for each side with 3 perimeters and only 56g with 2 perimeters. There is option to print one side with detent but there is no need for it really. I would recommend printing in petg if you got bigger nozzle the better and I would push up temps a bit to make it a bit stronger. I printed mine with a 0.6mm nozzle at like 0.4mm layer height and like 10 degrees higher than I would normally print Petg which is why it doesn't look that pretty but I want it to last rather than look good. All you need to put it together is either velcro straps as I used:https://s.click.aliexpress.com/e/_ooNz3bFor velcro-style zip ties https://s.click.aliexpress.com/e/_omdfLy9or reusable zip ties like these https://s.click.alie
