Prusa i3 MK3 Extruder Stepper Cooler Rework

With the work done by CG-Tech, I intentionally remixed this design to allow for direct attachment of the heat sink/cooling fan to the e-axis without relying on double-sided tape. To achieve this, I opted for M3-15 bolts that can be secured directly to the existing filament sensor cover. Using a Noctua NF-A4x20 fan, I routed it to the 5V rail located conveniently below the reset button on the EINSY board.
