“If you have medium to large hands, and (an) aggressive claw grip this (XM2) is definitely a consideration (and)'ll probably fit your hands much better than the OP1. I would still like to see just an OP1 Large, but with Endgame Gear releases, I'm not gonna hold my breath.”

So yeah, this was my inspiration for making this variation. Just to see how that would fit in the hand.
In the TinkerCAD screenshots, you will see the difference between the original OP1 (yellow), the XM1R (pink) and the resized OP1 (red).
The author remixed this model.
I sized the OP1 up to the size of the XM1R, which is still larger than the Razer Deathadder V3 Pro.
