Layer Cooling Air Pump/Motor Anti_Vibration Ball & Floating Mount

I have found a brushless version of the motor/air pump assembly that I have been using for over 8 months. I run the motor at 30% most of the time and has worked out very well for my setup. Still more noise than using a fan, but I do not like having a fan mounted on my Smart Effector and taking up valuable real estate.
I made two versions of the motor/air pump mount:
***1. Using Anti-Vibration Balls.***
***2. Using a Float Style with Elastic Bands.***
I favor the Anti-Vibration balls
