This 3D-printed Bambu Ball features an impossible-looking passthrough design with a mesmerizing spiral split. At first glance, the two halves seem completely disconnected and impossible to reassemble - but with a simple twist along the axis, they seamlessly screw together! A perfect illusion piece to surprise and impress, blending clever engineering with fun. Check out my other designs:
