My take on a replacement Buddy Cover with cooling fan(s). Installed twin Noctua NF-A4x10 24V 40mm fans. No voltage convertor board/adapter required. Printed with 3DXTECH PETG-CF filament, using PLA for the supports. Pretty close to the antenna mount, but it fits. Board and MCU temperatures significantly reduced. Pictured temps are during a build with an ambient air temp of ~28C. Very satisfied with the temp improvement. No more stalled builds due to MCU overtemp.
The author remixed this model.
Added an additional fan, and replaced exit slots with exhaust ports.
