This is a simple sleeve for a US light switch that turns it into a hook when it is set to ‘off’.

I made this because I have two switches, but only one of them does anything, so I figured- why not make use of both?

It is fairly strong, but I wouldn't recommend hanging something like a backpack from it. It's perfect for simple tools, signs, or keys.

It fits very snug on my switches here in the US (6.5mm x 7mm) and requires no glue.

I printed this in white PLA, and with a small amount of force it slides right on.
