A little tool to be able to turn the stopcock valve if stuck (which it usually is :)

Summary
While attempting to fix my dripping toilet water tank, I came across this corner valve that I was supposed to close, but it wouldn't budge since it had not been moved for 20 years. Due to some genius engineering on the manufacturer side, it's placed real close to the side wall so that you can't really grip it. It "offers" something like a slit on the top that looks like you could operate it with a big flat head screw driver, but since the knob is made of plastic, it only ruins the cap. It sure would have worked with a pipe wrench, but would only have ruined it even more.
Post-Printing
Since the final design has the Geberit brand name embossed in one side, I thought it would be fun to give it a quick paint job. It might either answer a curious question before it is asked, or lead to some interesting talks as well.
I can recommend nail polish for some quick and dirty paint jobs.
How I Designed This
OpenScad is my tool of choice. I took one picture with the phone for later reference and a couple of notes with a caliper and got to work. First part I designed was the "nut" of the knob, then printed it for ~2 mm and tried it on. It was a perfect fit right away. Then I designed the rest of the tool.
I had my mind set on how long the tool needed to be (just big enough for my hand to fit) and I thought it might be a useful additional feature if the drive part would be hex. Either for more grip in the hand, but also to be able to put a wrench on it and reef like a 200 pound gorilla. Although this will probably tear the tool apart.
The current design allows for a 16mm spanner up to 32mm spanner (if you have) to be put on, and certainly anything in between, so it's ought to be compatible to imperial freedum units, if Geberit is even a thing in the US...
