I've designed and printed 3D models to replace the central console ashtray with a cubby hole.
I released the source 3D models so that anyone can modify them and create their own custom ashtray replacement (no need to only have a cubby hole).

The files can be downloaded from thingiverse here: https://www.thingiverse.com/thing:3513550

 

But where would you keep your cigarettes ashes?

 

That's actually a really nicely made part! I just got into 3d printing, and haven't made anything for the G yet... You got me thinking.
