Modeled after a real casting of the spindle fixture.The clips are sold without mounting holes, but I have provided them as a reference.There are 3 machine screws in the spindle clamp. The middle one is offset and not for clamping the spindle. It is used to open the clip if it is too tight. It's not a bug that it stands out.Material: Aluminum 6061Processing method: CNC machiningSuggested post-processing in reality: bead blasting + anodizing black
