Windmill Tile Patterns (Roller & Stamp)

This roller aims to create the tile pattern shown in the image on XPS foam or a similar material, using 2mm edges to cut a groove. The roll itself is just over 6 inches.
The tile pattern is provided as a reference of what the roller shold create.

Updated 25/10/18;
Renamed the thingie to the realworld name of the tile pattern. Windmill.
Add 3 STL files.

1. The XY Distorted is the orignial file with the distortion listed above. The pattern repeats every 1 inch (about 25mm) in one direction and 1 1/8 inch (about 29mm) in the other direction.
2. The Roller, should give the pattern on a 1 inch grid, but it's untested at the moment.
3. The Stamp, again untested, should give a 1 inch stamp to cut into the XPS foam

Updated 02/12/21: Fixed the normals
