Car coasters
thingiverse
Coasters are the size of 12oz can bottom so they should work in any drink holder. You could expand them in the X and Y direction if you want them larger. The top has a honeycomb pattern to allow moisture to collect in the coaster. One says eject and the other says turbo. If you have other suggestions for what the coasters should say let me know in the comments. Easy to print with no support needed. If you like this and want to reward me you can download this from Printables at https://www.printables.com/model/381261-car-coasters at no cost. That will help me earn credits that can be used for free filament.
