Since the original series, Star Trek's reused ship models (and later CG models) as a simple way of saving time and money, particularly when it comes to ships employed by the alien-of-the-week.
Sometimes they could do a pretty good job of keeping people from realizing they seen this ship before, if enough time has passed, you give it a new paint ship, and add (or remove) some bits and pieces.
One nice example of a recycled model, I thought was the Bok'Nor from "The Maquis", which was the Merchantman originally, and a few other ships in between (and after).
Obviously the Merchantman was built years before the Cardassians had been introduced, so it's totally coincidental, but it shares the same basic "stringray" look that the Galor class (and later Hideki class) had, while having the stubbier, boxier look that's consistent with a freighter.
In retrospect, I'm surprised they didn't restore the model to this design (they'd modified it to be a Vidiian ship a year later) to use as the Groumall in "Return to Grace".
The CG Romulan drone ship was another good reuse. It had been a good six years since we saw it as a not-terribly-memorable alien ship in "The Fight". A little paint and some added detail and it worked fine.
A not so great example was the Tellarite ship. There wasn't anything wrong with the look, except that we'd seen it as the Xindi-Arboreal ship just the previous year. They should've used a design that hadn't been used so recently, in my opinion.
Any other reuses you think worked or didn't work? (Actually, if you noticed them, one could say they didn't work).
