📱 Ultimate Acoustic Phone Amplifier & Stand

Transform your listening experience with this sleek, 3D-printable passive acoustic amplifier! Designed with both aesthetics and functionality in mind, this stand naturally boosts your phone's volume while adding a touch of geometric elegance to your desk.

🌟 Key Features

• Acoustic Boost: Specially designed internal sound chambers amplify your mobile audio without any electronics.
• Charging Friendly: Includes a dedicated cutout at the bottom for your charging cable, so you can keep the music playing indefinitely.
• Multi-Material Look (No AMS Required): The honeycomb grilles are designed as separate parts. You can print them in a different color to get that premium look even on single-color printers!
• Optimized Geometry: Tested for stability and clear sound projection.

🛠️ Print Settings

I achieved great results with the following settings on my setup:

• Printer: Bambu Lab A1 (or any FDM printer)
• Nozzle: 0.4 mm
• Layer Height: 0.2 mm
• Infill: 15% (I used Lightning infill to save filament and time while maintaining structural integrity)
• Material: PLA (Silver and Black used in photos)
• Supports: Not required for most printers.

🔧 Assembly Instructions

1. Print the Main Body in your primary color.
2. Print the Honeycomb Grilles on a separate plate (ideal for adding a pop of color!).
3. Final Touch: Apply a tiny drop of super glue (Cyanoacrylate) to the edges of the grilles and snap them into the front openings.
