This object is meant to be used for educational purposes. There are 4 seperate .stl files that must be printed in order to make the entire design work. Once put together, the "TriTile" acts as a slider to show that "Tri" is the prefix of both "Cycle" and Angle". The prefix "Tri" means "three". By adding tri in front of these words we can see that a tricycle has three cycles(wheels) and a triangle has three angles.This is a simple slider that can be passed around during class to help students visualize the use of prefixes in the english language.
Using PLA, the print will cost ~ $1.15.
There is no commercial variant for this specific object.
