Summary

Its a basic magnetic stirrer, tried to make it as simple and easy to print, its not going to use too many material. it works great for how simple it is.
I used a simple 12mm x 25mm DC motor powered by 2 AA batteries and for the Magnets I used a side by side configuration with 8 2mm x 8mm neodymium magnets for the stirrer. I coated the magnets with hot silicone so they dont get rusted
