Coaster holder has been designed to hold 4 coasters.

Change the color on the 3mf to whatever your liking is. I prefer the macron colors purple,yellow, pink and blue. A few company's offer a nice range of these such as sunlu and overture.

The measurements of the coaster stand has been measured with rubber feet on each coaster which can be seen in the photo. These can be bought from amazon of your local diy shop.
