Update 19/09/17: Improved version 2.0 here: https://www.thingiverse.com/thing:2542351
Triangle learning/teaching aid. Lets you try-angles :)
- Shows all the side lengths and angles to help in exploring properties of "types" of triangles (equilateral, isosceles, scalene).
- Sum of angles exercises
- Template to draw "arbitrary" triangles (inside edges are smooth)
- Side lengths from ~75mm to ~135mm
Pieces snap together, you'll need three of each.
Big version in the works: https://www.thingiverse.com/thing:2520435
I used no supports or bed adhesion, 0.2mm layer height, i3 clone.
