Saw a fake product once that advertised this combo in one tool. Decided to make it real. Think it started as a remix of two different models but eventually I just did it from the ground up. Designed probably a year ago and forgot about. Saw the 20 cig smoker device and knew this would be the perfect companion piece.
Designed around use of a penny or dime to take the brunt of the abrasion/pressure against the bottle cap when opening. Insert the coin into the slot with some glue to keep it in place. The print file attached fits a dime and it needs to be pressed into place with an adjustable pliers like knipex, or a channellock wrench.
Currently printing a prototype in PLA+. 8 walls, 6/8 top and bottom solid layers or something like that, 40% gyroid. It's less than 10g in this format, so there's no good reason not to print it totally solid. Support in the coin slot will probably be a pain to remove, so minimize that pain by using 3 layers interface at .3 spacing and use a pick to pry out enough to grab with a side cutters or pliers and then pull it out slowly until the slot is empty.
Use responsibly, my beveraged friend.
