This is a AR Grip based off a very popular brand, 3D Scanned and made functional, it works perfectly, can use original grip screw and detent and detent spring when swapping over to this one. Yes it has all the right feel and curves as the (H)ogue grip does, but this is called the Rogue. Print this upside down, detent hole facing print bed, normal supports used for the bridge in the middle, could run no supports if your bridge settings are good though, brim is optional. 

Enjoy!
