This will turn about 60 degrees wait a minute and repeat, another words it not a continuous motion. It is for steeping ejuice.
Print Body with no support with flat side down.
I would not print this at more than 15%. Use a Outline/Perimeter Shell of 4 or more so the motor key will be strong. If using Simplify3D or other programs that allow you to have custom setting per layers, I would use Outline/Perimeter Shell of 4 or more for the first 7mm for the body to increase that motor key hole.
Print Sides with support.
If you notice the picture has the hexagon done wrong, bees would not approve. I fixed it in the body I uploaded.

The stepper motor shown will work with any DIY board(Pi, Feather, Nano, ...), the only thing to watch out for is the powering of the stepper motor board. The Uno is technically underpowered but I have not had any problems when connecting to the 5V output, you might want to power it through another power source or directly to whatever you are powering the controller(Uno) with. If you see problems with it not having enough power to turn, then try connecting the stepper board to a higher powered source. Make sure you connect the grounds to the controlling board(Uno) ground though.
