magnetic drive centrifugal pump
thingiverse
use 6mm diameter high temperature magnet from ebay. normal magnet will not work above 80 degree c. the printed part is only good for cold water. for high temp application milled one with aluminium and trying with delrin to speed things up. the with impeller is milled delrin. will drive and control with outrunner+esc and arduino. still waiting for the 1000kv 2212 outrunner though.
