Plinko with Replaceable Pins/Pegs (Galton Board, Binomial Distribution, Bean Machinese)

3D model description

### #Plinko Board with Replaceable Pins/Pegs (Galton Board, Binomial Distribution, Bean Machinese)

This is an extended version of my previous Plinko Board design. The pins/pegs are now replaceable. Please use marbles less than 16 mm in diameter.

  1. If all are printed in one assembly, the pins can be removed and replaced with new ones. When a pin breaks off, please clean the hole and push in a new pin. If necessary, try a drop of school glue.

  2. If the board and the pins are printed separately, please push the pins into the holes, using, if necessary, some school glue.

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:
