A simple magnetic sample plaque using 8 x 2 mm neodymium magnets, meant to be labeled with 12 mm x 57 mm labels (Brother or Dymo).

Stack together for minimal storage space, use additional magnets to attach to your nondescript brown box filament, or attach to a whiteboard for easy viewing.

Four steps of varying thicknesses 0.6/1.2/1.8/2.4 mm to better judge translucency, overall thickness 3.0 mm.

Designed to be printed with a layer height of 0.2 mm magnet holes facing down.
