This set of 3D printed constellation coasters features popular star patterns — designed with a clever two-part system for single-extruder printers.

Each coaster is printed with a cutout-style constellation, and a simple insert (printed first) slides into the print during a pause-at-layer to create a contrasting background color. No multi-material printer needed — just an insert drop!

Perfect for space lovers, astronomy fans, or as a stylish home or classroom gift.

Prints fast, no supports, and designed to fit standard drink sizes.
