the tapped inside on the impeller is m14, it is printed so if your printer works good you can screw it on ( i used some silicone grease for easy mounting ) take care that the impeller is turning free.
there is a litle bit of support necessary where you put the hose on but i could easely drill it out.
watch the video how you put it together.
If you want to have it pump for a while you can put it on a piece of polystyrene so it floats on top of the water
also have a look at my other things, for more interesting stuff
