While loading a spool of filament into my 3D printer to print an extension cord hanger for my garage I moved an empty plastic spool and realized it could be used to hang an extension cord on the wall. This unintentional inspiration is surely not original but I wanted to share it with others in this space. It is a simple project depending on the style of spool. Drill a couple holes and attach with screws and a washer into the studs in a wall. You may need to drill a larger hole to fit the driver extension to install the screws. Some older spools are assembled with screws.
