6-Fold Plaques from Triangles by pmoews

Last crawled date: 3 years, 1 month ago

Here are four decorative plaques and the triangular based motifs from which they are constructed.
Six copies of a simple motif are rotated, each by a different multiple of 60 degrees, around a common axis. The six copies are then combined with openSCAD to form a plaque with 6-fold symmetry.
Seven stl files are provided, 3 simple motifs, and 4 sixfold plaques:
motif_11.stl a simple motif made of 11 triangles
motif_12.stl a simple motif made of 12 triangles
motif_18.stl a simple motif makde of 18 triangles
plaque_11.stl a plaque derived from motif_11
plaque_12.stl a plaque derived from motif_12
plaque_18a.stl a plaque derived from motif_18
plaque_18b.stl a plaque derived from motif_18
The openSCAD program that produced the plaques is an experiment suggested by the nice way that the triangular based terdragons combine to form six fold arrays - see thing:69361. It contains 9 motifs and uses a simple method for choosing rotational axes. The motifs and a few examples of the translation method are included in a pdf file.
