About this 3D model

His lid unscrews to reveal a hollow interior. His feet, legs and key are all movable. You print them separately, and screw them in to the body. Once you have screwed a piece in fully, it can be turned forwards or backwards, as the threads pass into a void inside the model. Pieces can be removed by pulling gently and un-screwing. Assembling the model requrires some care. First make sure the threads are as neat as possible. Screw in gently by hand. If there is too much resistance, unscrew a bit and screw back in repeatedly. You do not want to break the screw off in the thread.
