I made this insertion module to put inside the bracket next to the steering wheel. I designed this originally for a Nissan Micra K12, but it can probably fit some other bracket in other cars.
It also haves a small hidden compartment on the back side of the module, in which can be used to store small thing inside.
The length is 95 mm, the height is 40 mm and the depth is 55 mm.
It's designed to perfectly fit a 2 € coin and it fits cards of the traditional size.
I printed this in PETG, but because of the hot summers a filament with higher temperature resistance can be used.
The author marked this model as their own original creation.
