Rifle Grip and trigger coffee holder

I am calling this a remix because that is how it started. I just wanted to add a grip to to the yeti holder. When I printed it there was no place for your index finger. I scrapped the holder STL and started over in fusion. Then I molded the Ar-15 grip to the trigger and holder I made. It is 88 mm in diameter and fits a Yeti coffee mug. If you need another size let me know in the comments. I wish I knew how to use openscad to make it a customizable size. Sorry.
