Simple Household Solid Color Propeller Blade Accessories – 1.4-Inch 3-Blade PC Propeller Set

For small-scale household appliances, hobby drones, or model projects, finding a lightweight propeller that fits standard 1mm shafts is essential for smooth operation. This set of four polycarbonate propellers offers a compact 1.4-inch (31mm) length with three blades for balanced performance. Available in clear, gray, purple, or red, these accessories provide a straightforward replacement or upgrade option without complicated fitting requirements.

Features and Construction

Each propeller is built from polycarbonate (PC), a material known for its transparency and consistent shape. The design focuses on practical dimensions and standardised hub measurements for easy installation.

Material and Build

Polycarbonate is a rigid plastic that holds its shape well under typical low-speed rotation. The blades are moulded to a consistent pitch of 1.1, which determines how far the propeller moves forward per revolution, making it suitable for small-scale applications where predictable thrust is needed.

Size and Practical Fit

With a length of 1.4 inches (31mm) and a shaft diameter of 1mm, these propellers fit motors designed for miniature setups. The hub diameter is 5mm and hub thickness is 5mm, providing a snug mount. The 8mm mounting hole allows for secure attachment to standard propeller adapters.

Uses and Placement

These propeller blades are designed for simple household or hobby use where a lightweight, compact rotor is required. Their small size and multiple colour options make them adaptable to various projects.

Event or Professional Use

In educational settings or prototyping workshops, these propellers can be used to demonstrate basic principles of aerodynamics or for small-scale robotics. The four-piece set provides spares for repeated testing without needing frequent reordering.

Everyday Home Use

For home hobbyists building small fans, cooling systems, or decorative items, these propellers offer an easy-to-fit component. The range of colours allows for visual customisation to match project themes or personal preference.

Benefits and Buying Value

This set delivers multiple units in a single purchase, reducing the need for multiple orders. The use of PC material helps maintain consistent blade shape during light-duty operation.

Reuse and Low Maintenance

Being made from polycarbonate, the propellers resist warping under normal indoor temperatures and can be reused across different projects as long as they are not physically damaged. No specialist tools or adhesives are required for installation.

Why Choose This Product

The combination of standard 1mm shaft fit, 1.1 pitch, and 5mm hub measurements makes these propellers compatible with many common small motors. The inclusion of four pieces in a single set provides immediate backup stock for ongoing projects.
