Kinetic Spiral – Đối Trọng Con Lắc Động (Dynamic Pendulum Weights)

Overview

This expansion pack introduces alternative pendulum weight designs for the Kinetic Spiral system.

Designed for the original Kinetic Spiral Wind Chime:

Different shapes create different airflow behavior, pendulum response and movement characteristics under changing wind conditions.

These weights can be used with the original Kinetic Spiral Wind Chime model or as standalone hanging kinetic objects.

Features

• Alternative pendulum weight designs

• Different aerodynamic movement characteristics

• Designed for the Kinetic Spiral system

• Standalone hanging use possible

• Lightweight kinetic motion

• Modular interchangeable setup

• Support-free printing

• Indoor and outdoor use

Included Parts

• Aero pendulum weight

• Open-flow pendulum weight

Compatibility

These pendulum weights are designed for the original:

Kinetic Spiral Wind Chime

The weights can be attached using the same suspension method as the original pendulum system.

Different shapes create different movement profiles and airflow behavior inside the spiral structure.

Standalone Use

The pendulum weights can also be used as standalone hanging kinetic objects.

Depending on suspension length and wind conditions, the different shapes create their own movement behavior and airflow response outside of the main spiral system.

Printing

• Material: PLA or PETG

• Layer height: 0.2 mm

• Recommended wall count: 3

• Infill: 10–15%

• Supports: not needed

Assembly

Attach the pendulum weights using a thin string connection to allow unrestricted movement and natural pendulum behavior.

For best performance, use lightweight print settings and low-friction suspension points.

Notes

The movement behavior depends on:

• Wind conditions

• Weight distribution

• Suspension length

• Print weight and material

The more open designs generally react faster to airflow, while larger surface areas can create slower and more stable pendulum movement.
