Parametric Subwoofer TPU Anti-Vibration Feet

🔊 Parametric Subwoofer / Speaker TPU Anti-Vibration Feet

A custom-designed parametric isolation foot specially shaped to decouple subwoofers and heavy audio speakers from floors or furniture, eliminating low-frequency cabinet resonance and room rattling.

The design combines a solid mounting block with a hollow half-cylinder arch that acts as a natural spring/elastomer when printed in TPU.

✨ Features & Design Highlights:

• 100% Parametric (OpenSCAD): Easily customize width, depth, base height, and arch wall thickness in OpenSCAD or Printables Customizer.

• Optimized Arch Geometry: The hollow half-cylinder converts vertical resonance into controlled lateral flex.

• Mounting Flexibility: Designed for easy double-sided tape mounting (e.g., 3M VHB), avoiding any drilling into your subwoofer cabinet.

🖨 Recommended Print Settings (Optimized for TPU 95A):

• Material: TPU / Flexible Filament (TPU 95A recommended)

• Print Orientation: Print lying flat on its side profile — NO supports required!

• Perimeters / Walls: 3 walls (crucial so the arch remains elastic under load)

• Infill: 10% - 15% Gyroid or Cubic

• Layer Height: 0.2 mm

• Top / Bottom Shells: 4-5 Top Layers / 3-4 Bottom Layers

💡 Installation Tips:

1. Thoroughly clean both the TPU top surface and the bottom of your subwoofer cabinet with Isopropyl Alcohol (IPA) to remove any oily residues.

2. Apply high-strength double-sided tape (such as 3M VHB).

3. Align all 4 feet in the SAME direction for uniform load distribution and symmetrical deflection.
