This is a very basic holster for a Glock 17 that is intended for modification. It was created to be perfectly at spec for a practice pistol and thus may fit snuggly for other guns, I suggest printing at 110% scale to ensure a nice fit. It should be used as a base model to add or take away from to have your own personal ideal holster. The Inventor .ipt file can be found at http://adf.ly/1ZPlMs in case you'd like to modify it.
