  • 3 608 bearings: 8x22x7 mm.
  • 3 M4 bolts: 15-40 mm in length (recomended flathead screw minimum 20mm
    in length).
  • 12 M5 bolts: 20 mm in length (I used one 20mm screw and one 25mm screw for
    each planet gear).
  • 7 M3 nuts
  • 7 M3 grub screws: recomended at least 6mm, smaller ones might fall out.
  • 3 Aluminium rods: 8 mm in diameter. 85, 75 and 93 mm in length (doesn't really
    matter, but by using this dimentions they will have the perfect length and stick out
    equally)
