Charger Holder

I use this charger:

But it has an issue. The charger is heavy enough that it frequently falls out of my extension cable, so I decided to make a fix. This holder simply slips over the charger and extension cord, then a rubber band can be used to secure it in place.

The charger is roughly the same size as a 65W MacBook Pro charger, so this design may or may not work with other similar sized chargers. The openSCAD file should be simple enough for anyone to tweak to their needs.
