The motor I chose, after about 10 minutes of running, gets quite warm. So much so that I can not keep my finger on it for more than a moment. I was not concerned as much with heat buildup in the cabinet as I was with the long term effect of the heat on the motor itself. I found a fan on Amazon, noted in the
Bill of Materials, which I felt would work well for me. It has 3 speeds, very quite, and is USB powered. All I needed to do was figure out a way to mount it.
Once again, back at my 3D printer, I printed out this stand. It straddles over the motor, allowing the fan to blow down onto the motor and has a recess for the fan itself to help keep it secure. The fan is bolted to the platform and the platform is bolted to the motor bridge.
Not sure what speed I will run the fan at, probably will start at the middle speed, and I can add a heat sink later if I need to.
