To print this model you need 10 berings. You can use this old berings from your 3d printer, if you don't have them, it's time to change them :).
You have to remove the plastic from one of these, like that.
If dimensional accuracy of your 3d printer is not perfect and shaft is too wide to fit in the bering, you can use sand paper.
If shaft is too thin or you have sanded shaft too much, you can wrap thread on the shaft between the gears as a thickness.
You need a peg to join output 1, output 2, output 3 and output 4 model. You can use a toothpick or the plastic wire, but you need to heat it and stretch it to make it thinner.
