This design follows the Helmholtz resonator approach: a hollow chamber with specific "necks" (ports) that dissipate tire cavity noise. It is designed as a curved segment that fits into the drop-center well of a 20" rim, using a flared base to wedge into the rim's geometry so centrifugal force keeps it seated.

Design Approach

Curvature: The segment is arched to match the internal diameter of a 20" wheel's center well.
Chamber: A hollow internal volume with internal ribs for structural integrity.
Retention: Flared "wings" on the base to clip into the rim channel.
Tuning: Parametric neck diameter and chamber height to adjust the frequency response.
Modular Assembly: You can print several of these segments to cover the circumference of the wheel.
Printability: It is best printed on its side (profile face down) to avoid needing excessive supports for the hollow chamber, or with minimal supports for the ports.
Printing Recommendation:
Material: Must use ASA or Nylon.

Wheel Helmholtz resonator

This parametric curtain is built for full adaptability in any interior projects. Simply grab and move the drivers to adjust its behavior. If you want to DUPLICATE the curtains you have to duplicate the curtain parametric collection so the keyframe works DON T USE INSTANCES . It supports full dimensional scaling customizable opening and closing and a wind pose for dynamic fabric effects. The curtain can be trimmed from the bottom to fit a wide range of windows or doors includes detailed stitching for added realism and features full color customization to match any design aesthetic. Note that for realism purpose this asset can only fit opening form 0.5m to 2.5m. If you want smaller or bigger windows you will have to resize the main xyz empty.

Neuron Network Mesh, ML - 3D Model

This 3D model represents a Spur Gear, one of the most common types of gears used in mechanical power transmission systems. Spur gears have straight teeth that are parallel to the axis of rotation and are widely used for transmitting motion and torque between parallel shafts.

This model demonstrates basic mechanical CAD modeling techniques including gear profile creation, extrusion, and parametric design. Spur gears are commonly used in gearboxes, mechanical drives, industrial machinery, and automotive systems.
