Diff oil level measuring tool?

Apparently there is a tool shaped somewhat like an Allen wrench which functions like a dipstick to measure differential oil levels when replacing diff oil. Should be very simple to duplicate. Can the tool be purchased from Ineos? Alternatively, Is there a photograph of the tool floating around showing shape and dimensions so I can fabricate one?
 
Why do you want to buy such a tool? Make one.! All you need is a wire hook with a leg length of approx. 35 mm on the short side. If you then fill the differential with exactly 2.1 liters of oil, the oil level will be approx. 23 mm below the filler opening. You can always check the oil level using a corresponding mark on the hook mentioned above. However, unless you do have an oil loss in the differential area, there will hardly be any reason to check the oil level. Given the price of the differential oil (approx. 5 euros per liter), it should be much easier to simply change the oil every 25-30,000 km.

This is not !!! the INEOS tool, but it should be similar. But make sure you do not drop the tool into the differential !

Id say this is a minimum not a maximum. I'd fill until it drips from fill hole like every other diff out there. Otherwise if I can squeeze my pinky in the hole and get a drip of 90w on it then it's also good.

Keep in mind this oil is splashing everywhere even at 5mph. So slight variations in oil level will not make a hill of beans difference up or down. Just changing caster from min to max will change how the tool reads.

Fill it till it drips and run with it.
