Most famously appearing (briefly before going kablooey due to Klingon shenanigans) as the USS Grissom in Star Trek III

Note: Since originally posting this years ago, I've created my own, more detailed and accurate, version of the Oberth class which includes variants of the ship and Blender source files. You can find it here: https://www.thingiverse.com/thing:4766389

This is based on the "U.S.S. Grissom" model I found here: http://www.trekmeshes.ch

To get a clean print I broke it up into a large number of parts. I've been sticking with 1:2500 prints for ship models, which for this is quite small (~6cm). Still, I think it came out quite well.

You should print two copies of the nacelle, as they are identical. Unlike all the other ships I've cut up, there aren't clear connection points for the nacelles and saucer, so you'll need to eyeball the correct place to glue them together.

Note that the way I've cut up the model, connecting the primary and secondary hull can be... challenging. A larger model may be easier to assemble.

STL is in 1:2500 scale.
