Coasters modeled from the companion cube from the videogame Portal. There are 3 ifferent coasters, a regular one, a flat one which is probably best as a coaster because it has a flatter surface, and the flat coaster in separate parts for multimaterial/multicolour printing. There is also a holder for multiple coasters, this can hold about 9-10 of the normal coasters and even more of the flat versions.
The coasters are 100 x 100 x 6 mm each
I used Blender to remix the original STL and clean it up in a few places before creating each of these files from it.
The author remixed this model.
