More Cat Tiles

Here are five cat tiles based on plane groups p1, p2, pm, pg and cm. See thing 155268 - Two Cat Tiles. The patterns came from things 54736 and 56813 - Cat Coasters 01 and 02. OpenSCAD programs like the one used in thing 151488 - Child's Puzzle 5 - were used to cut a repeating unit from a large plate.

Ten stl files are provided:

tile_p1.stl and 4_tiles_p1.stl
tile_p2.stl and 4_tiles_p2.stl
tile_pm.stl and 4_tiles_pm.stl
tile_pg.stl and 4_tiles_pg.stl
tile_cm.stl and 4_tiles_cm.stl

Multiple copies of the tiles can be printed and assembled as an aid to the study of the plane groups or to make interesting patterns.

The patterns are based on my interpretation of the plane groups using information taken from the International Tables for X-ray Crystallography, Volume I Symmetry Groups, pages 57 through 72; Published for The International Union of Crystallography by the Kynoch Press 1965. Errors are always possible. Note that there is some freedom in the selection of the
