They are larger cup holders than the original ones, which we can all agree were too small. I also added another slot bin to hold stuff like a phone or wallet.
The difference between the two files is that one does not have the raised nubs in the bottom of the cup holder. This is if you want to add the rubber cup holder inserts in the bottom. The other file has the raised nubs that are normally found at the bottom of the cup holder to redirect spilled drink so the bottom of your cup doesn't get sticky.
The author marked this model as their own original creation.
