Because I never use the cupholders I increased the space of the storage compartment in the center console. I bought this item from a German forum colleague. But he ended the production because the 3d printing duration was nearly a day.
Here the old and new situation:
Since my phone always overheats on the wireless charger I use the charger in the armrest. I had to get a slim connection sideways so that I can close it in there. This conversion would be epic for me. Although the best would be to keep 1 cup holder.
