The model is split in to several pieces to fit on to a printer with a build volume of 25 x 21 x 21 cm or 9,84 x 8,3 x 8,3 in. (Example Prusa MK3) All parts are rotated for optimal printing with minimal supports. Besides the printed parts you only need some filament strips and 6 mm black electric wire (for the side wire detail). You can see more details in my build video: YouTube
The model is split so you can print all parts in the right color and then assemble it.
Edit 24.04.2022:
Use 3-4 perimeters for the black rods and go really low infill and max 2 perimeters for all the parts above the head, otherwise it will be too heavy. If your parts end up to heavy check out this remix by JPMakesStuff: Link
