pump angle grinder

thingiverse

The tapped hole on the impeller is M14. If your printer works properly, you should be able to screw it in place. I used some silicone grease for easy mounting, which worked well. Be sure that the impeller turns freely. There is a small bit of support needed where you attach the hose, but I was able to drill it out easily. You may want to watch a video on how to assemble this piece. Here's a link to one: https://youtu.be/LrGiP-t-qq8 To get the pump running for a while, place it on a piece of polystyrene so that it floats on top of the water.
