I broke the clip slot on the driver’s side marker light of Isis (my 1990 BMW 325is), and I didn’t want to buy a whole new assembly ($32+ shipping). So, I modeled the broken portion of the assembly from the passengers side clip which is still in tact and 3D printed it.
I removed both assemblies, and measured the passenger’s side assembly with a cheap gauge and guesstimated what I couldn’t measure. I modeled the section in Autodesk Fusion for Mac and uploaded the model to Shapeways.
