Thanks all, I really appreciate the positive feedback!
I plan on scanning most of my parts I have lying around and uploading the files to grabcad or thingiverse for others to do as they wish, but I don't have free time like I used to and scanning certain parts takes a considerable effort to get a decent STL/OBJ file, and can take even longer to reverse engineer an accurate parametric CAD model.
Got the nav control, aux inputs, and sport/eco mode switch installed with my printed parts. Needs a little tweaking but they're good enough for now.
