Winch Handle Key

The filler caps for water and fuel on my boat use a winch handle to undo them, but you need several turns to undo them, which is basically not possible with a 1 foot long handle! So I needed something smaller. I found the original filler cap wrench by Beoga, but the handle was still too big, so I remixed it with a smaller key style handle.

Just to add, it floats if you drop it overboard as well, which is better than the winch handle does!
