A DZP mk2 left handed holster. I got this model on the DZ website but you have to put in a bunch of info on it and it's kind of hard to realize it's a thing because it's not on any 3D websites so I thought I'd put it here :)
Use M3 screws to screw it together, you'll probably need to cut 3 of the screws short to fit the pivoting part.
My video on it:
