LPG Adapter car door holder

I made this holder for three LPG adapters to fit in my car door (Dacia Logan MCV) but expect that it will fit in other doors as well, the holder will hold the following (short) 10mm thread adapter types :
- Bayonet
- Outer thread
- Euro

As there was some room left, I added an drawer to store coins or spare fuses

Materials needed:
2x M4x40 screw for the joint.
