There are two versions: stackable and non-stackable. The non-stackable is a bit shorter in z direction, and slightly more elegant. The stackable version is the one you want if you plan to print more than one.

Coaster is large enough for champagne bottles. (If you find a wine or champagne bottle that doesn't fit, let me know and I will provide a larger design.)

Here is a smaller one for glasses: [https://makerworld.com/en/models/37717#profileId-36196](https://makerworld.com/en/models/37717#profileId-36196)

XL version, up to 115mm diameter: [https://makerworld.com/en/models/448688#profileId-355507](https://makerworld.com/en/models/448688#profileId-355507)

Here are some Voronoi coasters that stack with the spiral coaster: [https://makerworld.com/en/models/195914](https://makerworld.com/en/models/195914)
