As discussed in this thread on page 3:
I want to try to design and 3D print a nice looking add-on for the M3 front bumper. It's not going to be a grille. Please let's put aside the discussion whether it's needed or not, that has been discussed already many times.
I finally found the time to 3D scan my M3 front bumper, you can find the file here:
For the moment Thingiverse did not activate the 3D preview, not sure why, hope they will do it later.
What I can say after comparing my scan with the M3 3D model found here:
Is that my scan does not fit exactly the front bumper on this model. I'm quite sure my scan is closer to the real thing, I've compared it with a picture of my M3 from the top and the curvature of my scan matches while the curvature of the 3D model does not.
Anyway, i'll be using my scan as a foundation for my 3D print and the 3D model for the overall design integration.
Looking at it, i'll try to re-use these basic lines:
As my car is black, I'll try to chrome the final part and have a black Tesla logo in the middle, a bit like on this draft rendering:
I'll post progress as I'll go along.
-1: scan the front bumper - done
-2: design the 3D parts
-3: print them and check fitting
-4: assembled the 3 parts
-5: polish and prime
-6: chrome and paint the part and install
I found some chrome paint that seems to be giving a pretty decent look:
Check out some reviews on Youtube. I've ordered a small qty. We'll see.
