Seat Cordoba / Ibiza 6K1 front grill screws

Hi all,
let me introduce my brand new model. It is square-headed screw for Seat Cordoba / Ibiza front grill mask. I decided to design it and print it because all used grills I have seen have missing screws for fixing grill to fender and its almost impossible to get them separately. They are specific because they have square head.

For modelling I used screw model from Michaltrow here:

Then deleted head in MeshLab, modelled square head in Solid E
