Christmas themed drink coaster or tree ornament 3D print model

These are STL files for four Christmas-themed drink coasters or tree ornaments: A Christmas tree, a star, a snowman, and the words Merry Christmas. There is a small hole in each one for a wire hook or thread so they can also be hung from a Christmas tree. There are two files for each model. The Base STL file is the main object. If you have only a one-color printer, you can just print this for a coaster/ornament with the image engraved on it (see pictures). If you have a two-color printer, combine it with the matching Fill STL file for a two-color model. These would make great early Christmas gifts.
