The original Aoyue WQ tips are shorter and nicer, but T12 tips are way cheaper and easier to source, so I have for a long time wanted to do this mod to be able to use them.
WARNING: The thermocouple in T12 tips is different, so you have to be careful when setting temperature (I have to set 250C to get about 320C when using the T12 tips). Other than that, the mod works just great.
The modification requires:
In the tip connector, repurpose the pin making contact with the leftmost ring, so it now contacts the second ring (starting from the left) in the T12 tip (that is aligned to the third ring in the WQ tip).
3D print this part and replace it inside the handle. Otherwise the T12 tip will not fit, because of one of the two wider rings it has along its body.
The modified handle works for both the T12 tips and the original WQ tips, since rings 1 and 3 (starting from left) are internally shorted on WQ tips. But anyway my recommendation is to keep an unmodified handle for the WQ tips just in case.
