This model provides custom replacement inserts for the Bachmaier Fidelity ear plugs, available in two functional variants:
Included Versions
Solid insert Offers slightly stronger damping than the original strong membrane insert (probably ab bit less dampening than maximum) when printed in PETG with 0.1 mm layers, 5 walls, 100% infill, and mild over‑extrusion (~103%). Ideal for users who want a bit more reduction without fully blocking sound.
Spiral sound‑inlet insert Features a small spiral channel that allows controlled airflow and sound transmission. Its damping effect sits roughly between the original light and medium inserts when printed in PLA+ using the same settings.
Printing Notes
Tested with PLA+ and PETG
0.1 mm layers, 5 walls, 100% infill
