About this 3D model

Model made for mi kids, they found a bit difficult to put it together, because it takes some ability to keep the first piece of each layer in place, you nee to hold it while you put the next. To make the puzzle "toddler friendly", I glued the pieces of the second and third layer by pairs, and now is very nice for them. For older kids, just keep it as it is. Hope you enjoy this model :)
