Take off the triangular black cover, reach in there with a pair of spring calipers and measure the threaded ring. Make your wrench the same OD as the ring, measure the width of the slots the same way. Use a depth mike from the face of the chuck to get the depth of the slots.

Pick another diameter inside the chuck that's larger than the ring and make the other end of the wrench fit that. Make a loose slip fit, enough to help pilot the wrench so it doesn't wobble all around. Also give yourself some way to grip that end, they can be hard to hang on to.

5 minutes to measure and sketch it up, nothing to it.

I've got a B206 so I can't give you the numbers or I would.
