Keep your umbrella or pole rock-steady in the sand with this 3D-printed sand screw anchor, a smart, portable, and easy-to-use ground mount for beach days, camping trips, or other outdoor setup.

Model Description

This model is a modular sand screw anchor designed for strength, stability, and easy printing. The main body features a hollow helical screw that digs securely into soft ground or sand, providing a sturdy base for a beach umbrella, antenna, flagpole, or even a portable satellite dish.

The anchor is made up of separately printed parts for convenience and durability:

Main Screw Body – Printed in two 229 mm sections for easier printing. The parts are aligned and bonded using printed dowels and glue or epoxy for a strong connection.

Fordable Handles: Serve two purposes:

-When positioned horizontally, they act as a lever to twist the anchor into the sand.
-Once in place, they flip up vertically to clamp around the umbrella shaft.

Large Hand Nut – Tightens the handles against the umbrella to hold it firmly in place without tools.

Hardware Needed:
You’ll need two M6 × 45 mm bolts (round-head Allen key type) and two M6 nylock nuts to fasten the handles securely to the anchor.
The design requires minimal print supports — only the top section of the screw needs light support for best results. (Print Settings document)

Design Concept:

The Umbrella Sand Screw Anchor is built with practicality and multi-use versatility in mind. Its helical auger design provides exceptional holding strength while the flip-handle clamping system offers quick and tool-free operation.

Beyond securing beach umbrellas, this anchor can be repurposed as a universal outdoor mounting base, perfect for:

-Mobile or field antennas
-Lightweight satellite dishes
-Temporary flags and event signage
-Garden poles or shade structures

With its compact, printable, and reusable design, this model is a must-have for anyone who loves the outdoors and wants a reliable way to secure their gear.

Print Setting: The main screw is printed in two sections of 229mm each glued together with the dowels. I added an STL of the complete main screw for reference. See Print Settings document
