Steeping Mixer

thingiverse

This will turn about 60 degrees, wait a minute, and repeat; it's not a continuous motion. It's designed specifically for steeping e-juice. Print Body with no support, with flat side down. I wouldn't print this at more than 15%. Use an Outline/Perimeter Shell of 4 or more to ensure the motor key is strong. If using Simplify3D or other programs that allow custom settings per layer, I'd use an Outline/Perimeter Shell of 4 or more for the first 7mm for the body to increase the motor key hole. Print Sides with support. If you notice the picture has a hexagon done incorrectly, bees wouldn't approve. I fixed it in the body I uploaded.

The Uno is technically underpowered, but I haven't experienced issues when connecting to the 5V output; you might want to power it through another source or directly to what you're powering the controller (Uno) with. If you see problems with not having enough power to turn, try connecting the stepper board to a higher powered source. Make sure you connect the grounds to the controlling board (Uno) ground though.
