Description

Bmw reverse (rds\non-rds\bavaria\business) audio device side covers. OEM-number: 65 12 6 907 823 This device can be used on Bmw E30\E32\E34\E36. Reproduced with the example of original part. Perfectly fits and holds on its original place. After print, part needs some sanding (at least, for better paint adhesion). I used 220grit. And some black structure paint for plastic. Fusion360 source-files (*.f3d) attached.
