Magnetic 3D Coordinate Axis Reference

This magnetic XYZ axis model is a practical and compact tool designed to support the understanding of 3D coordinate systems, ideal for use in robotics, CAD, engineering, and STEM education. It uses the standard RGB color coding—Red for X, Green for Y, and Blue for Z—to clearly represent each axis and follows the right-hand rule, making it a reliable reference for spatial orientation. Each axis is assembled to the central connector using instant adhesive, and the model includes slots for 8mm x 3mm neodymium magnets, which are easy to find in most hardware or online stores. These magnets allow the model to firmly attach to metallic surfaces, such as robot arms or workbenches, making it perfect for practical demonstrations or positioning references. The central node is printed in black, and the model is fully optimized for easy 3D printing without supports. The axes are designed with thicker walls and increased infill to improve strength while keeping print time efficient. With a compact
