A quick one indeed. You could make it based on the existing LanLan core but I think it's cheaper to just print the entire thing, so here we go: 50mm Dino Cube puzzle on Shapeways
Printing it based on the LanLan core would require the pieces to go deeper in to the puzzle, using more material. In this design, the core is simply hollow so it probably uses less material. Plus, the LanLan core is not free either.
I'm not going to print it myself, but maybe some of you will like it. Edge length is 50mm like an original one.
