### #Hyperboloid Pencil Holder / Cable Organizer
The hyperboloid is an amazingly simple yet rich mathematical object. The basic idea is so easy to demonstrate to school students using a few pencils or a cuboid (see my other designs). In this design, I wanted to highlight the symmetry and playfulness of a hyperboloid in a pencil holder, which can also be used as cable organizer, just for the fun of it. It holds 10 school pencils (up to 8.5mm in diameter). The hyperboloid is designed to allow pencils to move freely so students can play with it.
A stand can be used to keep the pencils from falling out if so desired. You could even glue it to the hyperboloid with a drop of super glue. Alternatively, you could just print one with a solid bottom.
It is about 76 mm tall and 74 mm wide at the top and the bottom. It can be stopped anywhere during the printing process for a partial yet functional pencil holder, if you like.
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/.
