Magnetic Stirrer V2

This is version 2 of our DIYbio magnetic stirrer.

A video of it working plus assembly instructions can be found here: https://youtu.be/e-usZzoXpTo

It is a big piece of equipment so it will be an equally big print job. There are many smaller computer fan-based magnetic stirrer designs available including our original design here: https://www.thingiverse.com/thing:2059400

A graphic is included comparing the sizes of V2 with V1.

We made this larger version to stir up larger vessels for soap processing, hydroponics, and other larger scale projects. It also still stirs the smaller jars we've been using for our original magnetic stirrer design.

We also included 2 stir bar designs. The bigger stir bar design using 13mm neodymium magnets works well for large quantity stirring.

**Improvements Include**

* larger platform
* sturdier platform to hold more weight
* 12V DC motor + motor controller for better speed control
* easy to customize magnet rotor
