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.
