For example, if there was a Shift X of 10%, normally the space between subsequent tiles would be 10%, 20%, 30%, and so on.
A random factor can also be added.Įxponent: Changes the exponent factor z so that position of each tile is x (or y) = (1 + "shift")z.Īlternate: The shift alternates between being added and subtracted.Ĭumulate: The previous shift is added to the new shift. Shift X, Shift Y: Adds (or subtracts) to the tile spacing in units of bounding box width and height. The following options are available to add or subtract space between the tiles: With the default parameters, rectangular tiles are arranged so that their Geometric bounding boxes are touching. The Shift tab allows you to vary the spacing between tiles. The OpenSCAD file is fully parametric in case you want to modify these. As the pattern gets larger, the ratio of rhomb1 to rhomb2 tiles will approach the golden ratio (~1.618), because math is awesome. The arcs are formed by thin slices out of the STLs they only go halfway up so you can tell which side is the top. The arcs also represent the maching rule, so lining up arc segments helps to figure out where pieces can go. It's easy to get stymied (for instance, nothing can attach to certain parts of the black star). I can still print upwards of 30 tiles per hour.Īssemble. This would be a perfect use for an Automated Build Platform, but mine isn't attached right now. Using Multiply, I managed to cram 16 of rhomb1 onto a TOM build platform and 18 of rhomb2 (it helps to use some negative separation with rhomb2). Turn off fill in order to print just the perimeter (this makes them print fast and snap together easily).
