Felix Grauer, a creative currently getting a masters in architecture at the Cologne Institute for Architectural Design (CIAD), has designed a LEGO key holder that anyone can recreate. A fun do-it-yourself project, it is much more functional than some would initially believe it to be. In place of classic hooks, Felix Grauer has attached the keys to special LEGO pieces that snap on and off of the larger LEGO plate mounted on the wall.
Although Felix Grauer's version is already quite basic, a person can theoretically make an even simpler version. The adorable use of 'keys!' can be done away with, which may be helpful to those who have limited amount of LEGO pieces to work with. Either way, Felix Grauer's creation is playful and clever.
