a) Fasten the F694ZZ flange bearing, driven wheel and following acrylic plates
with an M4*25 screw and an M4 self-locking nut in the way as shown below.
b) When completed, the assembly
should look like the figure below.

tighten the nut or else the wheel
cannot turn flexibly. Neither too
loose, in case the gap between the
parts is too large.
