The first two times I tried to use this tool it became stuck onto my tool head so stiffly that I had to rip apart the model to get it off. This could be because I was using a fairly stiff/tough PLA, but regardless of the reason it was dangerous to my machine. I had to use far too much force to get it off and nearly ripped the fan out.
To solve this problem, I simply removed the tab of material that locks in under the extruder fan. This was enough to make the tool slide on and off easily with no positive retention. I have found that if you fully insert the tool, such that the front face wraps all the way around the head of the M3 bolt holding the fan on, then that friction is sufficient force to keep the tool in place during use.
