You should have got 30 bearings in 3 tubes.

The on the top of the arm that has the motor mounted to it. The hole that the motor shaft goes through doesn’t get a bearing, only the bottom hole for the motor. All others will get a bearing on the top and bottom.

I made this mistake but caught after assembling one arm.
