there are several things, one is that both sides of the grip are mirrored in the model, but they are different in the real one. Also just in the part where the charger meets the cannon there are some ventilation windows or so. A part from the width of the grip that i really feel its too wide , and its because there is a stepp over it that it´s not in the 3d model. And of course the mechanism and hinge for the stock that in the model is just a tube and in the real one is quite more complex mechanism.
Nothing really important, i love how mine looks, and it´s worth the price if you want one with less building complexity as the one from thingiverse, but a bit less screenaccurate.
Some of those things have been updated, and just now, I've release a foldable stock with a sliding mechanism.
Here are some of the visible changes in the design :
front vents, engravings
Left side mechanism
Foldable Stock
Of course if you have already purchase the previous version, I'll send you a free update !
