My Dodge Ram 1500 cup holder is made too weak in my opinion and was easily broken. This is the part that broke. I modeled it and printed a replacement. The part was a bit complex and has lots of curves, but this version is holding together so far in my truck. Feel free to improve upon it. I will provide an updated version should the one in my truck be found insufficient. Good Luck and I hope this part helps someone.
Here are the files to print your own replacement if you have access to a 3D printer
