This design is based on dimensions of the cages used in our facility’s high-density ventilated rack system and would need to be modified to fit cages used in other facilities.
Other general tools and supplies used: rotary tool (Dremel), Loctite 401, soldering iron (Weller WES51Analog Soldering Station, Sparks, MA); surge protector; multiport USB hub.
