I should have been grading lab reports, but instead I made this key holder with some Legos. I screwed some picture frame hooks into a few full-height blocks (2×4, 2×3, 1×4) and attached a large base to the wall. Put some key rings on the Legos, attach the Legos to the base, key holder. My favorite part is that I can add whatever creation I want to the base plate as long as it can sit vertical, which is always true because it’s Legos. This is a simple spaceship I put together in a few seconds.
