Summary

This is a derivative of Madox's Mini Centrifugal Pump, http://www.thingiverse.com/thing:4839

I simplified the design and adapted it to be printable on a makerbot without support material.

I also modified it so that the motor from an old CD-Rom drive can run the pump. These motors are all about the same size, and anyone who likes to take things apart more then likely has a few laying around.

In the photos I am powering a 6 volt motor with a 3.5 volt battery. I imagine more power would equal more water moved.

Instructions

1) Print out all three parts, the Base, Impeller and Casing.

2) Drill out the center of the impeller so it fits on the motor's shaft

3) Use a knife to cut the support tower out of the center of the casing

4) Press the motor firmly into the top of the casing

5) Press the impeller down onto the motor shaft, but not all the way. Leave a little space between the top of the impeller and the base of the housing.

6) Power the motor and use sandpaper against the spinning impeller to smooth out any high spots

7) Press the base on

DONE!

The real magic of this, is that if you have the motor, it takes less than a half hour to download, print, and assemble.

Good idea bur WHY DO YOU DESIGN A SQUARE OUTPUT ???
With a cylinder output and input, your pump become universal because everybody can fix pipes on it.

I'll design a pump ...

Oh my god. We can print our own pumps now...

How did you edit the original stl files? I wanted to make a few modifications in order to attach tubing to the pump, but am not sure how to edit stl files

Imagine making this model with a rod that connects in such a way that the motor isn't inside of the housing.. This way the motor itself doesn't come into contact with water ;)

i like your testsetup with half the motor submerged

is it my imagination, or is the rotor inveted from what it should be?

Why is the exit square? You said you made it to print on a MB. We can print this without support and circles too.... :-D

NOw you just need to put this in your U-Boat...

Hey! Very cool! I suggested the idea of modifying the design to fet a cdrom motor. Thank you, this is great! Well done, I'll print it right now.

Now to go dig around in my computer junk box for a CD drive...

Great work skimbal , very easy to print :) Just need to do the cleanup and try it out!

By the way it might be possible to add a "connector" to standard "aquarium" tubing relatively easilly, i wiill upload the variation if it works!

Thanks again :)
