A standard Rhombic Dodecahedron has 12 sides. This puzzle has 18 because the 6 center cubies do not continue the planes of their four adjacent edge cubies to a point. Instead, the center cubies are flat, creating a new plane, but are stickered as those the planes were continuous. Each edge is the center of a hexagon. It could be viewed as truncated rhombic dodecahedron. THis shape is also known under the name Chamfered Cube.
Apparently, this is not a custom-built puzzle. It was available in retail shops in exactly this shape, although there were some colour-placement variations.
The so far earliest known point in time this puzzle was mentioned was in Cubic Circular #3 by David Singmaster in 1982.

This puzzle is part of the series "Octgonal Edges". All modifications of this series are made by truncating an 3x3x3 on its edges. These truncations are symmetric as in the mass produced octagon from which the series takes its name.
The technical signature (Octagonal Edges 3A5E8A00145E97) indicates where to cut the original cube.
Without the keyword "Extended" it is a variant made only by truncating the original cube. With the word "Extended" some sides left over from the original receive additional extensions to "delete" some of these remaining faces.
The extended variant of this puzzle is the completed Rhombic Dodecahedron.

No later than 2012 another mass produced version (under the name "Mask Cube") hit the market.
