I made a 3d-models of a three cute dinosaurus cookie cutters for 3D-printing and making some cute cookies: Stegosaurus, T-Rex and Diplodocus. Actually there is six 3d-models - with and without stiffening ribs (which are used for more stable and accurate cookie cutting process), you can see them all on the screenshots. The dimensions of dino's is: T-Rex - 100x100x8 mm; Stego - 100x75x8 mm; Diplo - 100x78x8 mm;
If you have any questions, feel free to ask me! :)
