This is my newly finished Xenomorphix. It was casted with smoothcast300Q and the mold were made from oomoo 30. The masters were designed and printed by twistypuzzles member Mindstormscreator. It uses a mini 3x3 as a core puzzle. The faces are very flat and the puzzle turns well. Occasional lock-ups occur but nothing major. The puzzle is very stable and I am pleased with the results. Here is the video:

This is the third Xenomorphix, isn't it?
Well done!
