I'm curious if it could be used with Park Tool's Universal Crank Puller to remove the crank arm fixing bolts--there's just over 1cm of space on the 15mm hex-ed part of the crank puller 'stud', which is between the 8mm hex bit / crank arm and the rest of the crank puller stud.
It works!
The plastic-coated version is about 1.25cm wide, but it fits over the crank puller stud and between that and the crank arm with room to spare--my initial measurement was a bit on the safe side, I guess. The flat part of the 3wrencho is short enough that it doesn't hit the pedal when you turn it, and it's angled so your hands aren't so close to the crank arms / chainring.
It took quite a bit of force to pull off the crank arm, but that may be because I haven't done that in over a year. Nevertheless, the 3wrencho / crank puller combo felt solid the whole time.
