I recently broke one of the tuner's knobs of my guitar and print a replacement...
There are some little holes to reinforce the internal structure of the hole, to make sure it will not shear if the knob is a little tight to turn.
The bolt diameter is 4.2mm and the knob fits tight and have to be pressed on, it is not a fault, it has to be a tight fit.
