INSPIREcomposite, nice work man. I am a big fan of what you have been able to accomplish. You are definitely one of my heroes! I would like to talk CNC with you some time. I am definitely heading down that road at some point. I'd like to know about your new machine.
As far as the kit goes, it is funny but I have recently learned first-hand, people don't really want/need kits. It is a nice and clean idea but it doesn't really work. They usually only need individual parts. It is totally understandable that some people already have acquired some parts and others just don't want them for some reason. For instance, I am probably only going to use a front LP670 bumper and possibly a rear LP670 bumper on my build.
If you don't mind saying where your original 3D model came from, I would be very interested. The thing is, I'm not sure if it will even fit a G28 without some modifications unless it was designed for that kit that from the ground up.
Again, nice work!
