3V Electric Motor Boat – 3D Printable Design

This is a compact and lightweight boat designed for 3D printing, powered by a 3V electric motor. The design is suitable for hobbyists and educational projects, offering simple assembly and smooth operation in calm water conditions.

Key Features:

Hull Type: Monohull with a flat bottom for stability

Power Source: 3V DC electric motor (can be powered by 2x AA batteries or a small Li-ion battery)

Propulsion: Rear-mounted propeller connected to the motor via a direct shaft

Material: PLA or PETG recommended for 3D printing

Assembly: Parts are snap-fit or require minimal glue; motor and battery housing compartments are included

Dimensions: Approx. 20-25 cm in length, customizable

Recommended Use:

Suitable for indoor water tanks, pools, or calm ponds

Educational STEM activities or DIY projectsOptional features can include rudder control, solar panel input, or modular top deck for custom accessories.3-Part 3D Printable Electric Boat – 3V Motor Powered

This is a modular 3D printable boat design powered by a 3V DC motor, ideal for beginners, makers, and STEM projects. The model is divided into three main components for easy printing and assembly:

Parts:Boat Hull: Streamlined body designed for balance and buoyancy; includes compartments for motor and battery placement.

Propeller: Optimized for low-voltage motors; attaches directly to the motor shaft.

Stabilizing Fins: Mounted on the bottom rear of the hull to improve directional control and stability in water.

Specifications:Power Source: 3V DC motor (compatible with AA batteries or Li-ion cell)

Recommended Print Material: PLA or PETG

Assembly: Snap-fit or glue-based connection; minimal tools required

Water Use: Best for still or slow-moving water (e.g., pools, tanks)

Applications:DIY hobby model

Educational tool for teaching basic electronics and fluid dynamics

Fun science project or weekend build

Assembly Note:The stabilizing fins should be securely glued to the bottom rear section of the boat hull using a strong adhesive such as cyanoacrylate (super glue) or epoxy, depending on the material used. Ensure proper alignment to maintain balance and directional control in the water.
