Step 1: Print Settings
For printing I recommend placing the amplifier upside down, with the sound output aperture resting on the bed and with the following parameters:
Resolution: low or medium (printing will take between 4 or 5 hours). Infill: 10%, Grille. Lower upper thickness: 0.6 - 0.8 mm. Supports: 5%, lines at 0.2mm distance. Rafts: 6-8 mm. Ensure correct leveling of the bed and a good hold with hair lacquer.
