Steeping Mixer

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.
