Duet Maestro enclosure(with Stock Ender 5 or Ender 3 LCD 12864F-3)

I'm using a single 120mm Noctua fan for cooling my Duet Maestro and the stock LCD that came with my Ender 5 printer. The design is quite modular, allowing it to stand alone or mount easily to different printers. The fan is positioned under the board to cool the stepper drivers properly, according to Duet3D. The airflow then rises over the top of the board and exits at the top of the case, with openings for airflow throughout. Since my Ender 5 runs on a 24v system, I'm using a buck converter inside the enclosure to power the 120mm fan. I secured the fan and LCD with M3 bolts and nuts, while the Duet Maestro board is held in place by Nylon M3 bolts with steel nuts. The lid of the enclosure is also secured with M3 bolts and nuts. The mounting plate uses M5 bolts and nuts to attach it to the case and 2020 extrusions. I made a fan stand to make the 120mm fan more stable and easier to mount, as it's at the perfect height for my Ender 5. However, once the mounting plate and underbody support piece are securely bolted in place, the enclosure is extremely stable without the fan stand, so I leave it in place anyway. All ports on the Duet Maestro are easily accessible, and there's a slot to view the Status LEDs. I'm still using the stock Ender 5 enclosure for the PSU and ran longer wires to bring in power. The other wiring is stock, with an extra 10-pin cable for the LCD and some DuPont jumpers since I didn't have the tools to crimp new ends for the Duet. I recently added a version of the enclosure without a screen and with ports facing forward for easier access.
