Equilateral Triangle with a linear extruded frame
thingiverse
looking to make a wireframe structure with interchangeable text panels. proud of using trig and rounded corners (thx, Mathgrrl!) .2 layer PLA. 10% infil (no supports) LOTS of separation. (old? filament, supports, maybe?) first step towards real designs. Thanks to: -OpenScadTutorial.org for all the preliminary instructions. -Mathgrrl for the cointrap rounded corners solution.http://makerhome.blogspot.com/2013_08_27_archive.html -Wikipedia for helping me refresh trig memories with fundamental images. http://en.wikipedia.org/wiki/List_of_trigonometric_identities#mediaviewer/File:Unit_circle_angles_color.svg -My Wife and Son for putting up with me while I play and learn. Instructions I wanted to make a keychain that takes advantage of 3D structures rather than just a 2D extrusion. This is a start. I started with a sketch in autodesk 123 and extruded but was having difficulty making cutouts. I switched to openSCAD and learned translate and rotate. (the reset view feature helped a lot as well) Added the spheres to round the corners and am looking forward to modularizing the code and creating more complex structures.
