My Led Bridge Lamp uses 5V addressable LED light strip, and it requires more amps than standrat wall-wart can supply. So I ordered separate 5V / 20A power supply for it and there is the covers for it. They provide good ventilation, sockets and on/off switch.
Original Prusa i3 MK2 kit
I use brim to prevent ABS from lifting corners up.
