Citroen C4 Red Bull multi can adapter

If you have a Citroen C4 like me (I have a C4 Grand Picasso CMP6) and you drink energy drinks on long car trips you potentially have my same problem: where to put the can while you drink it and after! The can holders (two in the frigobar, if you have the automatic transmission like me, and one between front seats) are dimensioned for normal 33cl cans like Coke, Pepsi, etc. but energy drinks (like Red Bull) have smaller diameter cans and are at risk of falling if put there and you brake.
So I made these can adapters where energy drinks fits perfectly inside.
But wait... energy drinks comes in different sizes...! That's why I made two pieces adapter:

• for big can is the main adapter that fits in the car can holder. Inside it a big Red Bull will take perfect place
• adapter for small can is ad adapter that can be inserted in the for big can piece to reduce the hole diameter and accept a small Red Bull can.

Now you'll have a perfect place where to put Red Bull cans when you drive :)
