About this 3D model

The coaster can be divided into two parts, mainly because iced water often produces condensation, and this coaster can separate the condensation from the table. The upper diameter is 75mm, not suitable for large cups, very suitable for small cups of iced American. In addition, with good printing quality, the rotating coaster can be used as a stress relief toy. Not suitable for hot water, the material is not heat resistant. The printing surface is too smooth, which may cause the upper layer to be sucked together due to the surface tension of water. The solution is to make some texture on the contact surface, but I am too lazy to modify it. Those who are interested can do it themselves.
