We traditionaly use syringes to fill classical Genesis. Here is the 2.3mm filling hole:

The idea was to make something simple to fill the tank fast from usual e-liquid bottle.
I used a piece of 2mm metallic tube taken from the old atomizer and 3 pieces of heatshrink tube:

Put them together. The small tip of metallic tube is needed as shown:

The prepared filling tube inserted into the old filling hole:

Now you can fill the tank without a syringe, just from the bottle:
