Frame外框

What it is

The frame is the outer body of a fidget: the part that carries the rails, magnets, pins or bearings. On many sliders it is the piece the plates move against; on some coins it is the outer ring.

Why it matters

Frame material and wall thickness shape weight, sound and stiffness. A stiff, accurately machined frame keeps tolerances consistent, while a thin frame saves weight but can ring or flex.
