After losing both of the parcel shelf clips for my Citroën C3, I searched for a replacement model. While I found a few options, they all seemed to fall out almost immediately. However, this design 'clicks' in and won't come out because of the hooks.

I have experimented with printing this model in both PLA and PETG. While both materials worked, PETG seems to offer superior springiness in the clips. Additionally, it may perform better with the heat inside the car. Best printed on its side with support.

Might also work with other Citroën model, let me know if that is the case than I will add them aswell, tnx!
