The previous owner of my Audi A6 C7 (Facelift) had lost a couple of the Isofix covers. I found a model online which works really well. Credit to the original author over at https://www.myminifactory.com/de/object/3d-print-audi-a4-isofix-cover-114524
Printed in Prusament Galaxy Black PETG. Best orientation for me was on it's side, with supports everywhere. This gives a great finish on the important outer surface.
