Modified OpenRC F1 2019 front wing

Slightly remixed front wing OpenRC F1 2018. (I'm unable to find the original, help! :( ) It's lightweight, it's nice, it's ... fragile. And it has two peaces. --- Added "stadard" front wing attachable to the holder. Added model for modifier. You can modify the wing model by this modifier in slicer, so central part of wing can be stronger, while rest of the wing can be thin and light.
