Simple fast filament spool hub

thingiverse

After building my Anet A8 3D printer, I conducted a series of test prints, both practical and unorthodox. This experience sparked an idea - designing my own custom spool hubs for printing filament. While there are numerous designs available, they often seem overly complex. In contrast, my own creation may be somewhat simplistic, but it effectively fulfills its purpose, is rapid to print, and conserves filament usage.
