I usually don't like to publish one-off prints like this, but it was so handy that I can't help it! My garage door opener plugs into an outlet in the ceiling of my garage. I don't have a 6+ foot ladder to reach the plug. One day, I had to unplug the opener for maintenance but had no way to plug it back in, so I ran a long extension cord. It stayed that way for a couple of months, and there was really nothing wrong with that setup other than, well, I just wanted it plugged back into its proper outlet! Since I had a hollow metal broom stick, I decided to quickly design something that could be placed on the end of the stick and use that to plug the opener back in. After about 5 minutes of design and less than an hour of printing, I had my solution. It was a little awkward, but it worked on the first version of the design!
