Tri-tetraflexagon / tetraflexagon for Flexible TPU Filament

Tri-tetraflexagon for Versatile TPU Filament A tri-tetraflexagon with six 25mm x 25 mm squares; note that the 7th square overlaps another to form a loop. I initiated this project as an experiment using versatile TPU filament, which turned out to be a fantastic endeavor. To print, please rotate as needed to fit the strip on the printer bed. Once printed, fold it in a way that allows identical letters (A or B or C) to appear on one side of the large square (see illustrations). Then, super-glue the two squares without letters for a tetraflexagon. Paper models are often used with children. However, in this instance, a versatile TPU model feels more appealing.
