For a Delta 3D printer I am designing I created these modules for OpenSCAD for quickly creating triangles. Thought I upload it encase anyone else wants to use them. Modules for:- Triangle, Isosceles_Triangle, Right_Angled_Triangle, Wedge, Equilateral_Triangle, and Trapezoid. Updated 8th Jan 2014 - Added support for different heights at each point of the triangle. This allows creation of wedges. Updated 9th Jan 2014 - Trapezoid now just a single polyhedronAdd this file to you OpenSCAD working directory and add the following line to you OpenSCAD files you want to use these modules in:- use ; Then you can use any of the modules. Help on each module can be found inside the scad file.
