Size: 100mmW X 100mmD X 143mmH May be used for a Science Project but more for fun with the children. Print in ONE PIECE; no assembly needed. Best with 3D Printers that print moving parts is preferred. Model may be re-sized. However moving parts may be an issue for some 3D printers when re-sizing. Do a mesh analyse before printing is advised. Like all children toys please use printing material that is child safe.
