AUDI A4 B6/B7 (2000-2008) cup holders.
Cup holders fits perfectly, just push it down and it fits tight, does not require any modifications.
Made it with professional 3d printer. The quality is one of the best you can achieve from this technology.
Fits RHD and LHD. Just push it and it will fit tight.
I made this to fit standard can size like coke, pepsi, etc. and for most popular cups like McDonald's or coffee cup from gas station (500ml/17oz)
Tunnel is made for AUX cable if you Audi has it.

Also have another cup holders version
