Dreikopftile

If you spot numerous fidget spinners on these photos: Congratulations -- you're wrong! These objects are simple wooden toys cut from 3mm plywood using a lasercutter. (Yes, the center hole is there just to deceive those fidget spinner enthusiasts.) The pieces tile the plane and can be cut with minimal waste. The pieces connect in a zig-zag pattern, and eight pieces form a ring. This isn't mathematically precise, but as it's wood, it easily bends inward to close the ring or ten pieces form a ring if bent outward. Two rings can be connected by adding four more pieces to form a cube (or a pentagonal box). Stacked cubes create columns. Columns can be joined at 90-degree angles. An arc (or a large complete ten-sided regular polygon) can be formed if short columns of cubes are connected with five-sided boxes in regular intervals. The SVG file also includes a layer containing four-headed tiles, intended to create useful strings of tiles that aren't possible with three-headed tiles.
