Origami, German Bell, Math, Geometry

3D model description

Origami or artistic paper folding is an engaging math-art activity. There are so many ideas one can learn in an origami task, from words, shapes, spatial thinking, symmetry, fractions, to proportionality. However, most origami projects do not lend themselves to 3D design or printing.

The German Bell is one of the few that I have tried to make a 3D-designed model of. It works very well with PLA or flexible filament. Once the template is printed, removed with a spatula, please GENTLY fold the square along all the grooves, trying not to fold them completely, though. Once the creases are flexible, squeeze the four corners and allow them to come together SLOWLY. Meanwhile, push the bottom out a little bit. There you go -- a German Bell. It is an entry-level 3D design project as a complement to the traditional paper model.

The thicker versions may work better, depending on the filament.

STEAM educator, learning from and working with K-12 STEAM teachers to explore new ideas of teaching and engagement. I firmly believe ART is at the core of STEM learning or all human learning! I owe my ideas and designs to the hundreds of K-12 children and teachers and university professors I have had the pleasure of working with, in multiple disciplines-- math, science,engineering language arts, social studies, early childhood education and more! All mistakes, of course, are mine! There is no warranty or liability whatsoever implied or explicit behind the designs or ideas. They are all posted for their potential educational values.

When working with children, please strictly observe all safety and health procedures! Please refer to the NSTA safety guides:
