The magnetic stirrer is one of the basic tools of any scientific laboratory, this one that I made in PLA because I use it only with cold liquids can also be printed in PETG for good thermal resistance. The body has a compact design with precise housings for the electronics, a stable base and a flat surface on which the container to be stirred is placed.The fan or DC motor (often recovered from old PCs or brushless fans) is connected to two neodymium magnets, fixed on a rotating disk. The whole thing is driven by a simple circuit with PWM regulator to vary the speed.The assembly is very simple just follow the sequence of the photos.To glue the magnets to the disk and then glue it to the fan use a good glue, two-component would be excellent. Also very useful for mixing e-cigarette liquids Materials and links for purchase 1 A 12V 90x90x25 mm Cooler Fanhttps://amzn.eu/d/iSCABgW1 DC sockethttps://it.aliexpress.com/item/1005002914520024.html?channel=twinner1 12V Power Supplyhttps://amzn.eu/d
