Where Does VOYAGER Get Its SHUTTLES?

Voyager was stranded in the Delta Quadrant. Alone and without Federation or Starfleet aid and their resources. So how in Q's name did they manage to carry so many shuttlecraft?
They get blown up or crashed so often in the series and the ship keeps producing more. Where are they coming from?
This question has been a fan criticism for years but one that I think isn't that big of an issue as we've seen all the evidence to explain this in canon already.
I think... hear me out...
