Mixed-Flow Water Jet (experimental prototype)

Edit: I realized accelerating the water already inside the impeller makes no sense as it creates extra drag, so I changed the impeller and stator design accordingly. Now it should be much more efficient.

This Design requires a lathe to machine the drive shaft

_____________________________________________

Furthermore, M4 bolts and nuts for the housing and a M3*10mm grub screw for the impeller are required (and obviously a motor and clutch)

I recommend filing the flanges and motor mount flat and sanding the inside of the jet pump.

Printing settings and material is not that critical, I recommend 1,2mm wall thickness and 20% infill and high quality pla or petg.

I made a video talking about the design and assembly: https://youtu.be/VVPTRJDVuTc

This is a very experimental prototype that might be better or worse than a common axial flow water jet. So far I only know that it works, but more testing in the future will be needed. I invite you to try my design idea yourself
