ISSUE: The crank rod doesn’t fit in the hole provided in the base.

 Correct!.  Gently ream out the hole until the crank tightly fits through.  if you’re close, you can try tapping a straight segment of 0.062 rod though it.  Be careful to support the base on a flat surface. Go easy, as it’s easy to cause layer separation in the printed part.  Don’t worry about it being too tight.  You want it to be tight so the rod doesn’t wobble.  All it needs to do is rotate., even stiffly.
