Stackable Coasters with the Devanagari Om Symbol

The famed Om symbol (https://en.wikipedia.org/wiki/Om) and utterance is used in yoga and other meditative disciplines and has deep spiritual meaning to many peoples. I brought back an appreciation of it after trekking to Mt. Everest Base Camp in Nepal.

The coasters are 1 cm tall, stackable, with an image 1 mm tall whose shape provides good support for glasses and bottles.

Two filament changes using contrasting colors are recommended. Otherwise, the effect is much lessened. The filament should be changed immediately after the last layer of the base, and then back again after the last layer of the symbol.

Files are provided for a single coaster (coaster_x1.stl), four coasters that fit easily on the Ender-3 standard bed size (coaster_x4.stl), and the OpenSCAD source code (see below). Printing four at a time helps because they can share the two filament changes.
