Thule tool adapter for roof box lift

We have a Thule 572 lift for storage of our roof tent. It comes with a hand crank for raising and lowering the platform. The only problem is, that it takes just about one thousand turn of the crank to get the platform down, and my laziness forbids me that kind of work.

Therefore this hook for a hand drill. The hexagonal part of the hook is 10 mm, as most hand drills is compatible with that and it seems to be plenty strong.
