I am going to be designing and printing my own version. But I would assume that you are not required to have the identical version. Having a vent and fan is ideal though to allow the heat to dissipate from the enclosure. The drivers do produce some heat and depending on how "hard" you are planning on running the arm, the drivers could produce more heat.
Thanks for your response. I’m working on making a custom panel with a nema enclosure and was trying to figure out if I needed a vent
