I remixed this wall hooks from this thingiverse post (https://www.thingiverse.com/thing:3545870) to add a Pikachu face for my oldest to hang his backpack on. It's been resized as well to make the holes 4mm for standard drywall screws. The 2 color variant adds filament changes at 2 points to allow for the outline and facial features to be a different color from the main body.
