This simple Key Hook is a great little addition to any home or apartment.

Attach it to the wall using 3M command strips or heavy tape like doubles sided Gorilla Tape (made by Gorilla Glue and can be found at CVS). https://www.cvs.com/shop/gorilla-double-sided-mounting-tape-1-in-x-60-in-prodid-172467

Requires no supports and prints in about 2-3 hours depending on your settings.

Note: The default version can not hold super heavy key chains. My key chain has a car key, an apartment key, a mail box key, and a plastic library card. If you'd like to hold larger key chains you may consider increasing the thickness of the key hook or setting your infill to 100.
