Buying tips: (1) Quantities are for one full arm — buy screws, nuts and bearings in packs; (2) Check current / voltage / body length on every stepper motor, the three Nema 23 sizes are NOT interchangeable; (3) Belts are HTD 5M, 10 mm wide, one each of 430 / 285 / 490 mm; (4) The 197 3D printed parts must be printed yourself (official STL) and are not listed here.
