Filament guide bracket

This upgrade replaces the original fixed support that often creates too tight an angle between the spool and the PTFE, causing kinks and filament breaks. The new bracket introduces a soft, raised guide that leads the filament towards the PTFE tube more linearly. The result is smoother feeding, less friction and a significant reduction in jams. The design is optimised to print quickly, with good strength and no need for extra hardware.
