So I have been setting up my Kaldi, and it is an amazing little machine. Only thing I didn't have was a cooler for my beans. I didn't want the one available by Kaldi, so decided to build my own.

Materials Used:
Tamale Pot from the Swap Meet
Small Cheese Cake pot
Pizza tray with holes
Piece of wood
Random pieces of aluminum
Fan motor, similar to my Kaldi Exhaust system
Really small geared electric motor

Check it out, still needs some adjustments, but cooled my 600 grams of beans in under 2 minutes.
Works really good.

Nice! As for the bean cooler location, are you planning on carving out part of the counter or build an extension of the bean release shelf?

Actually, I cut up a baking pan and use it instead if the paper plate. I just mounted the cooler with shelf hangers, and wired up the power button to where all the buttons are located. It's working great now.
