1. A 3D printed structure of an elastic material, the 3D printed structure having at least a first layer and a second layer, and the 3D printed structure comprising:
a first wall configured to deform when a first force is applied to the first wall in a direction of a first axis and configured to return to an original form of the first wall when the applied first force is released, the first wall comprising at least a primary structural layer and at least a first flexible layer; and
a second wall configured to deform when a second force is applied to the second wall in a direction of a second axis and configured to return to an original form of the second wall when the applied second force is released, the second wall comprising at least a secondary structural layer and at least a second flexible layer,
wherein a third axis of the 3D printed structure intersects the first layer of the 3D printed structure, the second layer of the 3D printed structure, the primary structural layer, and the secondary structural layer,
wherein the primary structural layer has a first rigidity and the first flexible layer has a second rigidity, the first rigidity being greater than the second rigidity, and
wherein the elastic material is stretchable or compressible without plastic deformation.
