These look more cute than scary, but printed at scale I'd hate to have a run in with a few of them in some drak and wet corridor or shipwreck. These printed beautifully at several scales up and down from the packaged file size. I used supports, but probably did not have to do so. The supports where a challenge to remove because of all the legs in the way, so you might want to be less liberal with supports than I was. I gave a few away to someone of the female persuasion (there's an in joke in there). She now has pet crabs. Used a Robo 3D R1+ and Simplify3D to produce my copies and they look pretty much as advertised. Again, bought these as a package deal on sale and feel it was well worth the few bucks handed over as I don't think you'll find anything like these at any FREE sites that provide game related STLs.
