If you’re into retro wargaming and 3D printing and you’ve never heard of Doctor-Spork, you’re missing out!
He has a really great selection of classic 3D printable terrain designed with FDM printers in mind.
There are a number of free items as well, just in case you want to try before you buy.
Did I mention buying? The prices are BEYOND reasonable. And by that I mean, lower than a reasonable dollar figure. The most expensive model is well under $10.

It’s not all sci-fi/40k stuff either. There’s plenty of retro-fantasy models available as well. Not to mention some tanks and other assorted vehicles.
If you’re looking for a model that authentically looks as if it was cut and assembled from a 90’s White Dwarf magazine, look no further!
