Smith Selector — Rotating Arrow Dial

A rotating arrow dial for selecting between two options (SMITH 1 or SMITH 2) on a 250×140 mm sign. The arrow pivots on an 8 mm shoulder with 0.3 mm radial clearance, held at mid-height by a felt friction ring that provides rotational drag to keep the selection steady. Assembly uses a single M4 button-head screw, wide washer, and M4 nut; the three printed pieces (ivory backing with five mounting holes, navy rotating arrow, and ivory shoulder spacer) print separately and can be optionally paired with ledge hooks or tabletop feet.
