Two Cat Tiles

Here are two tiles, one triangular and one square. They are derived from thing:151488 - Child's Puzzle Five. There is no puzzle here as the sides of the tiles are all the same and edges always match. As a result any number of tiles can be printed and arranged to show a large scale version of the pattern. There may be those who will find pleasure in placing multiple sets of tiles. The patterns were suggested by things 58639 and 61601 - Cat Coasters 03 and 05 - and are members of plane groups p4g and p6m. Four stl files are provided: tile_p4g.stl and 4_tiles_p4g.stl tile_p6m.stl and 3_tiles_p6m.stl
