This coaster can be printed in the collors you like. Mine are printed with these filaments:

• Esun Deep Black matte PLA
• Esun Light Khaki matte PLA
• Esun Matcha Green matte PLA

There are different sizes for the holder that you can chose from!

The inner diameter of the holder is 104mm so you can also only use that if you already have some coasters laying around.

I printed mine with an infill of 15%
