Our used car lacked a cover for the hole where the ignition key usually goes, but since we have keyless it was just a gaping hole. 

A few minuttes in Fusion and I had a click in place plate that covers the hole.

Printed in PETG on a powedercoated PEI plate to get the texture, but would probably be better in TPU

It is a bit tight to get in place, but I has been installed for over 6 months now and no issues.
