Coffee Cup Adapter

I got tired of having to hold my cup or put it somewhere where it could easily get knocked over so I designed an adapter that fits snuggly into a regular cup holder to hold coffee mugs or cups where they wont fall over or easily get knocked over. 86.68mm is the x axis size, it fits snuggly into the cupholder and to your coffee cup. If need be you can increase the size a tad bit if you have a bigger coffee cup and still be able to fit it.
