• Core Functions: When used as a children’s beach toy, it can smooth sand in sandboxes or along the shoreline, clearing away debris from the sand surface; it also serves as a compact gardening tool, ideal for leveling potting soil and gently aerating the topsoil.

• Specialized Applications: While some designs share similarities with baking tools—such as pie crust dimpling devices—they remain firmly rooted in their core purpose as sand play accessories or lightweight manual labor tools, consistent with the “sand rake” moniker.

Design and Material Characteristics

• Structural Design: Featuring a five‑tooth arc-shaped profile paired with an integrated handle, this design offers a comfortable grip while ensuring even tooth spacing, making it highly effective at leveling loose sand or soil.

• Material Properties: Crafted via 3D printing using PETG, this tool is safe, non-toxic, and boasts rounded edges—perfect for children’s use and even food contact.

• Customization Advantages: Thanks to the inherent flexibility of 3D printing, the dimensions and tooth geometry can be tailored to meet specific needs, making it suitable for a wide range of applications—from children’s toys to miniature gardening tools.

Cultural and Application Context

• Traditional Sand Rakes: Originally specialized tools used in salt production or casting industries, designed to loosen and distribute coarse salt grains or shape fine sands. Today, they’ve evolved into versatile playthings for children and practical tools for light gardening tasks, emphasizing both entertainment and hands‑on, low‑intensity work.

• 3D‑Printed Variants: Through personalized fabrication, these modern sand rakes retain the functional form and aesthetic appeal of their traditional counterparts while benefiting from lightweight construction and cost‑effective production—making them an ideal choice for home DIY projects or small-scale applications.
