About this 3D model

After making a metal heart puzzle in metalshop, my son designed a lighter and smaller one to be 3D printed. IMPORTANT NOTICE: WHEN SLICING THIS MODEL, SCALE DOWN TO FIT YOUR PRINTER BED. THE BIGGER THE BETTER. When taking this off the build plate, be careful and peel up one chunk at a time. If you need help solving the puzzle, here is a video showing the solution: https://www.youtube.com/watch?v=ZJjeh1XeBVw Have Fun!
