The Prusa XL is a powerhouse of a printer — but its stock Buddy Box cover traps heat in the buddy box. With no ventilation and no airflow, the electronics enclosure at the back of the machine traps heat, pushing MCU temperatures higher than they should be and risking thermal throttling or instability during long print sessions or in warm environments. The Bartallama3D™ Steel Buddy Box Ventilated Cover for Prusa XL with GDSTime 24V Fan is a drop-in replacement that fixes this from day one — no sourcing parts, no wiring headaches, just install and print.

Built around a steel cover with purpose-designed ventilation cutouts, this upgrade replaces the stock steel cover with something that actually manages heat. The included GDSTime 24V fan plugs directly into your Prusa XL’s existing 24V wire terminals — no voltage converters, no adapters, no modifications. Plug it in and your Buddy Box finally breathes.
