This is a pretty useful shotglass featuring high volume, a solid stand and mostly important numbers from 1 to 8 which are pretty necessary for counting drinks, useful in drinking games and whatever. The print will probably slice with some errors not affecting the quality of the product. If the settings were not perfect and your shotglass suffers from beeing not waterthight you can use aceton. But as this one is going to be a drinking glass, you can also use a little wax of some candles, heat it with a hairdryer till it becomes liquid and fills the holes. This should not leave any suspicion of consuming bad chemicals.
