About this 3D model

Over the last 2 months I've created these coasters in shapr3d, these coasters are great, work well printed from any material, I've printed them in PLA, PETG and ASA so far, and they all hold up very well, I do recommend hand washing them as I'm not sure they would handle the dishwasher, warm water and soap is just fine. The holder itself i designed to look like Spaceship EARTH. For multicolor printing, ive made my base white and use layer fill to color the top to make them pop. ive reversed it as well and made the base colored while the top white, i happen to perfer the color on the top half myself.
