This is probably a silly idea and not enough details but could really use someone to help with the below.

I have a Lexus es 350, 2010 model. The cup holders are terrible. I would like to get something made (a base) that would fill the existing cup holders (width, length and height) but it is not a perfect rectangle. the next level above the base will be the new cup holders. I would like two separate cup holders on this 2nd tier. Tall enough to keep my 40 oz Stanley to not tip over so about 3”-3.25” deep and the center of the holes to be at least 5” apart and no more than 6” so that two Stanley’s can sit next to eachother. I want the new cup holders to be standard size, so a diameter of 3”. I have pictures with measurements if anyone is interested in helping for $.
