A non-shape-shifting puzzle with a highly unusual axis system.

This puzzle has the shape of a trapezo-rhombic dodecahedron. That is the shape one gets when a rhombic dodecahedron skewb is turned by 60� instead of a complete 120�-turn.
This puzzle allows turns around 12 corners. Depending on whether these corners are of third or fourth degree the possible turns are 120�-turns or 90�-turns.
The two corners of third degree which do not take part in the trapezoids do not turn. There is no mechanical reason for this. It was just the inventors matter of taste.
This is another puzzle hard to understand. It is no jumbling puzzle since the twists are never blocked. It is not a fudged puzzle. Its geometry would lead into a jumbling puzzle if the cuts were placed deeper. The axis system reminds of a hybrid between corner and face turning hexahedron but half of the axes are twisted by the 60� mentioned above.
To increase confusion even further this puzzle contains "bridge"-pieces which are two seemingly different pieces that behave connected in reality.
