Marble Rings, Locked, Hungarian Rings

3D model description

Marble Rings,Hungarian Rings, Lock-up Version

Sometimes, one wants to lock up the marbles in the rings. To do that, one can pause the printing at a point close to completion, drop the marbles, and then continue to finish the printing. That is doable but inconvenient.

Alternatively, one can slice the middle part and then snap it on later. A drop of super glue might also be handy. The design can accommodate 24 marbles (15-16mm in diameter). There is also a 1-mm tolerance along the tracks.

Have fun!

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:
