Rear View Mirror Hanger Hook for Placards

I created this model to replace the hook portion of a cardboard rear view mirror placard. I have to hang and take down the sign every day, and the hook portion got damaged and was hard to use. The hook portion of the placard can be cut off, and it can be slid into this print. The hook is large and should fit more easily on the mirror.

Update Oct 11 2025: I added a print profile for a small vertical placard, modified by dengar256.
