speed champions display stand 6-8 stud

I updated the way the platforms of these stands work. There is no longer a distinction between SUV, F1 cars, and regular 8 stud cars. 

There are just two platforms. One that covers the 6 stud cars, and one that covers all 8 stud cars.

The main difference here is that there are different wheel pads for the larger wheeled vehicles which from what I understand seem to just be for the Ford Bronco and the Mercedes G-wagon, the wheels on those are 36mm in diameter and the rest of the vehicles have 24mm wheels.

Please note that the wheel pads have a tight fit on initial fitment onto the platforms, but after a couple of slides back and forth on the platform they fit really nicely and are easily moved around to fit the various wheel bases of the speed champion cars while not being too loose.

The platforms also do not need any supports to print so they all come out nice and clean!

Because of the updates to the contact points for the wheels, I find all my speed champion cars have a much more stable seat on the platforms. I can move a whole stand without much concern about a car or multiple cars sliding off because they were not situated as nicely as they could have!
