This is a 3d printed part. It fits great, looks excellent, works fantastic. I bought the grey version. Work the part in carefully, take your time. The seller’s video in the description is very helpful! Great alternative to dropping $100 on a replacement. Excellent value, fast response and shipping..

Works for E46 M3

Color: Black

Great customer support, fits like it should, is a nice detail that you’ll notice if yours is broken. Looks like OE. This is my first 3D printed part, I hope it’ll last another 20 years. Has lasted almost a year so far!

Flimsy, pretty obviously 3D printed. It's noticeably blue in color, but no one in the front seats will notice. This is good as an aesthetic bandage fix, but I'll go back to sourcing an OEM piece.

Poor quality.

Color: Grey

This is a waste of money. No communication from seller. It took super long to receive it and when I got it , it was a big disappointment. This is a junk.
