Dodecahedral Cups

3D model description

####Dodecahedral Cups

A local elementary school (Lewis) invited me to showcase 3D design and printing for a large group of young children on their "Discovery Day." I need some designs that are interesting and funny-looking to children, yet mathematically appealing. I thought of the dodecahedron, which I manipulated a bit to entertain the children.

They look nice and are easy to print. I think others might be interested in tinkering with them. So here they are.

Among the Files

0.The measurement (30mm, 20mm) refers to the circum-radius of a face pentagon.
1. Dodecahedral cup with a handle.
2. Dodecahedral cup with a handle plus an integrated straw.
3. Dodecahedral cup with a twisted neck (10mm)
4. Dodecahedral cup with a long twisted neck (30mm).
5. Three cups have "Lewis" on them.


  1. PLA filament works well.
  2. Flexible TPU can be used to make a flexible cup.

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:
