I've researched this forum trying to find a DIY cup holder. I found a few, but decided to do it differently. This looks kind of hokey, but it is a prototype. I've tested it for a few hundred miles and it works well. This holder was left over from stuff I had from my Harley days. After removing the handlebar bracket I lashed it (with wire ties) to the door pull bar. No holes were drilled in the door panel and it will not damage anything. Hope the photos attach.
