Two years ago I thought of a way to overcome the extremely shallow-cut problem of the Dino series that I wasn't very happy with. I realized that the pieces of the three Dino puzzles could be permuted in a different way as with this post:http://www.twistypuzzles.com/forum/viewtopic.php?f=1&t=23930
I believe the puzzles can be made by:
-Slice DRD by fixing the corners of the Rubik's Revenge and hiding the corner and edge pieces
-Slice DRT by fixing the corners of the 4x4 Megaminx and hiding the corner and edge pieces.
I do not claim these designs as mine and really wished if someone could make them as I don't have the time to learn SolidWorks as of now.
