Nice build, the case is 3D printed, and the electronics are all sourced parts. Figure this would cost about $10-15 dollars each. That said I got curious and looked to see if I could get one already made for less. And yes you can, for about $10 you can get one that is about the same as this one, with 6 stir sticks. This would be a tough call, if I had the parts, I think I would build, but if I have to source most of the parts…well…I think I would buy. Of course the “fan” version of this could be a good alternative.
