Windshield Wiper Fixer BMW E46

Hi,
Because my windshield wiper didn't wipe the windshield of my car correctly, I designed this thing. I fixes the wiper in its holder.

I added a few modells which differentiate in the size of the gap.

The "Auto Scheibenwischer-Fixierer (1,4) v3" is more stable. v4 and v5 are shorter than v3

The car in which I use this is a BMW 318i E46 (2004). Currently, I use the v5.
