spin mop bucket 3d model

Design a mechanical spin mop bucket system with a vertical press-to-spin mechanism. Main structure: - A cylindrical bucket with a flat bottom and reinforced side walls - At the center, a vertical shaft (diameter 20 mm, height 25 cm) Spin mechanism: - The central shaft includes a helical thread (like a screw) along its length - Around the shaft, a fixed internal guide sleeve with matching angled grooves - When downward force is applied, the shaft rotates due to the helical interaction Top assembly: - A circular spinning plate (diameter 16–18 cm) attached to the shaft top - Plate includes radial slots for water drainage - Surface textured for mop grip Return system: - A compression spring around the shaft (bottom section) - Spring pushes shaft back upward after pressing Base system: - Stable base with anti-slip pads - Optional ball bearing at shaft base for smooth rotation Materials: - Bucket: matte plastic (green tone) - Shaft: stainless steel - Plate: durable plastic with rubber
