Fidget square

Square that transforms into an equilateral triangle. 

The design was inspired by an illustration from a math book - Hugo Steinhous' “Kalejdoskop matematyczny”. 

Prints in place, without any support. Can be printed in multicolor using a single extruder 3D printer. 

To print in multicolor you should print 3 files one after another without taking the prints off the bed. First print “lines.stl”, then “color_layer.stl” and finally “main_for_color.stl”.

If you don't want to print in color just print the “full_square_body” file.
