Animal Tile Puzzle

cults3d

Can you fit the 16 unique animal silhouettes into the frame? Seems easy in theory, not so much in practise! Frame has been included as a solid base tray and as just the brim - use whichever suits you best :) Saw something similar but was too small for the better half, and all the existing animal tile tray puzzle stl's were too easy. I have not included a 'completed' image to avoid spoliers - if you need a solution pic I can send on request :)
