Telescopic Cylinder, seven stages, with 45° stoppers, diameter = 80mm; 60mm, height = 50mm; 20mm; 100mm.
Telescopic structures are simple yet mathematically appealing. I was playing with telescopic structures and came to realize that the stoppers inside could be made from 45° angles for smooth printing. The design process (on Fusion 360, for example), is fairly easy. K-12 students could learn how to use variables (parameters) for flexible design, constraints for intended geometric shapes, and rotation (revolving) for 3D construction. This is an entry-point 3D design project, featuring structures that are traditionally impossible to make in one piece. The result, however, is aesthetically motivating.
Please make sure the first layer is not too thick.
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: http://www.nsta.org/safety/.
