Umbrella Isofix mount

I've recreated the original model and added some optimized wall and rounded the corners to use less filaments. My template is set toprint in 0.24 draft and adaptive infill. Very happy with the result. Feel free to customize it using my model in Onshape : https://cad.onshape.com/documents/5facd3d45bddd1b5fe8fe4d8/w/1cac7725de6e41a9644f6877/e/6d1b73ee710a0c2e7b9b38c2
