Got my metal yesterday,,, enough to make a couple which is good. The smaller 3" ID tube which is better for the holder space wise is only wide enough for a can of soda. I'd need to find a new travel mug for this to work. The 3 1/2 ID is better but will take up the whole console area. I'll mock up both with the top plate and see what I like.
Also ordered my flip top arm rest from the UK. It's shipped already but lets see how long it takes to get here
