The 3D files provided are only for the support frame and magnet bed. To build this stirrer, you'll also need the following items: * A standard 80x80mm 12V computer fan * A power supply with a DC output of 6-12V; note that using 12V alone can be too fast unless paired with a resistor * A Teflon-coated stirrer (available on eBay) * Two rare earth magnets (mine were sourced from old Seagate Barracuda HDDs, but you can easily adapt it to fit different shapes) * A drop of hot glue * Superglue * A CD case The magnet bed is specifically designed for 2 magnets removed from a 40GB Seagate Barracuda 7200 HDD (available on trademe.co.nz for approximately $4.5), but you can easily modify it to accommodate different shapes. Magnets are simply pressed into the plastic bed, which is then glued to the fan using a hot glue gun. The top and bottom parts of the frame are bonded together with superglue. The frame clips onto a standard CD case.
