This is a purpose built tileable system of coasters to hold glasses. This solution is ideal to hold glasses with a base between 55mm and 60mm. The design is based on an octagon which means the coasters can be connected infinitely but with gaps in the middle. These gaps however have either blank fillers or ones which you can put a post into to hold a 30mm by 30mm square of paper to write on for extra utility. Have fun and Happy Printing!
