mug holder for Renault Trafic II vehicle

In vehicles in general, there is a cup holder,

but it is only designed for the cups you get from gas station coffee machines

As a result, mugs or cups with a handle don't fit

and so with every acceleration I ended up with the mug tipping over and losing my coffee.

I have designed an adapter to insert into the cup holder, allowing you to put a mug or cup (up to D90mm) with or without a handle and enjoy your homemade coffee in your favorite mug during my professional trips

:)

I hope it will be as useful to you as it is to me
