The flexible center console shelf on my '15 Ford Focus was just too shallow and I also liked to keep a pen easily accessible. I created a deeper shelf that could replace the factory one and also placed a shaft in one corner to keep a pen in but one that wouldn't lie flat and take up too much space.

I kept them modular so if one piece broke then only that one element would need to be reprinted. It also made printing without any supports or odd angles much easier. I originally printed in PLA but the heat in the car was too much so I went with PETG with much better results.
