Brass Motor Coupling (Hex Style A – 3.17 mm Shaft, M4 Thread) · 模型 74664
This is a highly accurate 3D model of a brass motor shaft coupling (Style A), designed for motors with a 3.17 mm output shaft and M4 threaded connection. It is a scaled-down version of the standard coupler used in various RC, robotics, and mechanical drive systems. Based on the real-world geometry of the original product from AliExpress, but modified with a 3.17 mm bore instead of 7 mm, while keeping the rest of the dimensions true to the reference. 📐 Dimensions (as per Style A): Length: 18 mm Hex Width: 12 mm Bore (shaft side): 3.17 mm Thread: M4 Side screw hole: Ø suitable for M3 grub screw (not threaded in model) 🔩 Use cases: Brushless DC motors 3D printers RC cars CNC machines Robotics projects I baught here - https://www.aliexpress.com/item/1005005470562301.html?spm=a2g0o.order_list.order_list_main.86.5f8a1802bExWMm#nav-specification
