Nalgene Cup Holder - Resize

I printed LovelySunny's nalgene car cup holder adapter, but found that it didn't fit in my cup holders. This version has a 84mm diameter base, roughly 3-3/16". Small enough to fit my cup holders. The original was oblong, which didn't seem to matter, and roughly 89mm.

This could still be greatly improved, but it got the job done.
