Spiral

The objects shown in the image appear to be additively manufactured (3D-printed) polymer components, likely produced using a fused deposition modeling (FDM) process. These components demonstrate a combination of functional geometry, modular design, and manufacturing experimentation, and they may serve as prototypes, mechanical elements, or educational demonstration pieces.Several of the components are cylindrical or prismatic in form and feature internal cavities, indicating that they are designed to fit over, house, or interface with other parts. The presence of hexagonal external and internal cross-sections suggests intentional design for torque transfer, alignment, or compatibility with standard tools or fasteners. Hexagonal geometries are commonly used in mechanical design to prevent rotational slippage and to enable efficient force transmission.Two of the orange components exhibit a helical or spiral outer surface, which may serve multiple purposes. Functionally, a helical profile
