Four different Maze Coasters. Why not entertain your guests with a maze, after you insist on them using a coaster? The STL file has all four coasters in one file. If it's too big for your print bed, just separate them into four gcodes in your slicer. The gcodes that are included are in PETG for the coasters, and PLA for the holder. The coaster gcodes also have a color change, so the maze stands out against the base.
