I was inspired the Ultimate Cupholder and created my own version. I used a bike water bottle holder (cage) from ebay and a plastic pants hanger from a department store. I trimmed the clips and hanger wire from the straight section of the hanger. I cut it down to 9.5" in length. I heated it to spread the hanger a bit to pocket the bike cage. Then I screwed them together and push the straight section under the center console side. I'm not sure plastic will be stiff enough but it seems very sturdy. A bit of testing is in order.
