I built this recently, took a lot of iterations, but it works very well. Now, its all 3D printed, but I took a few precautions. Given the heat, for the stirrer, I used a filament that has a heat deflection upwards of 205 celsius (PA6-CF). In addition to that I coated it in three layers of epoxy (FDA Food Safe Grade). Happy to answer any questions, help with a build etc. If you have interest beyond that, drop me a private DM on here please.
A few things I’ve noticed using this, in addition to cooling the beans much faster, it also eliminates A LOT more chaff. I’ve very happy with this addition.
Hopefully I can help some of you out as well. Here are some pics, and a few videos showing it in action.
