Update 19/09/17: Improved version 2.0 here: https://www.thingiverse.com/thing:2542351 Triangle learning and teaching aid. Let's try angles. + Shows all side lengths and angles to help explore 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.
