About this 3D model

I wanted to have a spool like the one from Bambu to easily respool my non Bambu filaments. There are many remakes with reduced filament usage, but most have an even higher printtime than the original one. So I came up with this Brick wall like design, which will handle the radial forces by the AMS very well, reduces the filament required a lot and also improves the print time. Enjoy :)
