Wall holder for a laptop power brick
A cradle that holds a power supply brick against the wall or under a shelf, keeping it off the carpet where it collects dust and overheats. It is an open-ended sleeve sized to the brick plus 1 mm of clearance, with 3 mm walls, slotted sides for airflow and a back plate with two 4 mm keyhole slots. Open ends let cables exit either way, and a slight inward lip on the front edge stops the brick sliding out when the cord is tugged.
Every charger has different dimensions, so a printed sleeve only works when it is drawn to your brick. Measure it, type the numbers into SpeakCAD and check the preview for free in your browser. Prefer a closed bottom or a second sleeve for a phone charger? Say so and iterate.
