Motorcycle cup stabilizer

This is to keep drinks from tipping over in my motorcycle saddlebags. I tried about 9 designs and this turned out to be the best (and simplest)

I saved some cups from various restaurants, from the largest to smallest as tests. It had to be something where I could drop it in while I was at the drive-through.

Glue it together, but don't use superglue (cyanoacrylate)
