This model is G1 key of Corsair K55. It is so that you can add whatever you want on top of that. So, it is exact replica of the key, but several changes were done to fit 3D printing. Currently, little hooks at the sides are breaking too easily for PLA, working on it. I would suggest ABS. However, since ABS shrinks, try different scale options to find the best fit.
