Pranja, you have forgotten to put 2 additional balls at around 4 o?clock !
So there are 2 balls missing at the right side ! Otherwise, yes, simular to this !

There is one ball missing, Stefan. This is necessary, otherwise one would have more than 1 ball on each spoke.  The ball at 11 o'clock 'skip's the 12 o'clock spoke to arrive at 3 o'clock.  Well, such an arrangement is not really possible because of the spoke spacing but, in any case, if balls travel from 12 to 3 you end up with more than one ball on each spoke (unless there is a gap).

Okay, Pranja, but
ONE ball is still missing !

You can pull back the spokes from 12 to 2 o?clock so the ball just runs out to 3
o?clock and then at 3 o?clock push out the spokes again, so each ball
will then be again in its normal slot.
This should work then.
It is just a matter of modifying the spokes at the right time !

P.S: Yes, at 3 o?clock will then always be 2 balls !
When the spoke comes back out again at around 3 to 4 o?clock,
it will push itself  back between the 2 balls
and then at the left side every ball is again single
on every spoke, so at the left side there is then only 1 ball per spoke again !
