Sometimes using a 3D printed part isn't ideal because of the way it is made, it is brittle. CNC out of aluminum would be a definite upgrade. If you guys ever need someone to draw up something on SolidWorks, let me know. I do this all day at work, and can export it to an IGES, STEP, Parasolid file, etc. I can get certain parts made as well. I did all the RnD involved to make replacement brackets for the GD chassis in order to retrofit newer roof racks. I have a couple of threads on NASIOC for them. I love this kind of stuff.
