large hub filament reel retainer

This is a remix of an excellent concept (originally created by https://www.thingiverse.com/thing:3478552) for securely holding the filament reel on an Ender 3 or 5 printer. I designed this version because I've been receiving new filament reels with significantly wider widths and larger internal hub diameters. As a result, the traditional retainer no longer fits properly inside the hub due to its smaller diameter and increased thickness. The added width of the reel also causes it to get stuck in the holder. To address these issues, I incorporated additional discs at each end and enhanced the structural integrity of the design. You can view photos showcasing this improved version with a narrower diameter but wider winding area.
