Ok, I know we all complain of the lack of sufficient cup holders in our trucks so I finally decided to make something for my full console. I took the regular cupholder and drilled out the cups with a 3.5" hole saw then trimmed it and inserted two single cup holders from Walmart, ~$1.50 each. To hold them in place I used expandable spray foam and filled with plastic putty around the outside. Since the cups are lower it has to sit further forward so I had to cut another cupholder to fill in the gap and to extend the mounting points. I painted it with Krylon Fusion I had on hand but need to find a better color match. Someone is working on getting something 3D printed so this will hopefully be temporary, especially since I need two more of these. Here are some pictures.
