About this 3D model
Summary I created this based on taking measurements from my physical key. With the blank take it into your favorite cad program and paste a photo in to size to trace. then trace it out with a spline and extrude to the depth of the extrusion on the tip. I was pleasantly happy with mine which was able to unlock and start my Jetta on the first print! Print Settings Rafts: Doesn't Matter Supports: Yes Resolution: 1mm layer height Infill: 20 Notes: I had to print mine at a funny angle for the slicer to slice it properly.
