MAGNET MOTOR ROTOR CYLINDER

I getting into magnets so i made a cylinder for testing.. its the v-gate type. not deep enough for perendev because of the holes. the size is 180 dia X 105 high so even a graber i3 can print it.. i used 10 infill at 0.2.. It uses 608 skateboard bearings 22X8X7mm.. easily available.. and you can use 5/16 rod available at home depot.. i am going to be using aluminum rod ... hope this helps somebody discover the secrets... hasnt been printed yet, 7 hours to go but i did dbl check the dimensions.
step and 123d files included if you need them.. enjoy
