This is a replacement trigger designed for the AEG ALT18B line trimmer.
It also includes the proper geometry for the safety button release to function as intended.
🔧 Compatibility:
Confirmed fit: AEG ALT18B
Likely compatible with Ridgid trimmers as well (AEG and Ridgid share the same parent brand), but I have not tested on Ridgid models.
🖨 Print Settings:
Recommended materials: PETG, ABS, or PC (for strength and durability)
Supports: Required (for the overhang section)
Infill: 40–60% suggested for strength
Perimeters: 5+ recommended for durability
