These are some coasters I designed for a gift. They are made to filled with Resin for a nice finish. I printed mine in PLA then painted graphite metallic. I used Rub n Buff for the crest and then resin with metallic flake to fill the coaster. There is one for each of the Hogwarts houses.
The photos attached were printed on a Creality Ender 3 pro with no name PLA filament from Amazon.
