I looked at about a dozen different models but most of them were too bulky for me. I need to print dozens of these things, so I wanted something that wouldn't tie up my printer all day.

This design not only prints like a dream, but like any good valet, it's right there whenever you need it. Once you've slipped it on, you'll never take it off again, because Wall Wart Valet is thin enough to stay in place, even when the charger is plugged into the wall.

Just wrap the cord like you normally do (around the ends, right?) but now you'll find some convenient fingers in place to keep the cord from sliding off the sides and coming unraveled. Plus there's a convenient clip to grab that pesky loose end.

Obligatory word of caution: if you plan to leave it in place, be sure you don't use conductive filament. :-)

Prints lightning fast in PLA at 0.3mm layer heights. Fast enough that you'll be giving them away as quickly as you can print them.
