Anet A6 Control board cover with 8cm fan

I borrowed inspiration for this cover design from tobbi007's creation, which was a remake of the original Anet controller cover with added fan mountings and a hole. I had it fitted to my A6 after noticing that the heatsinks on the control board were getting extremely hot during prints, particularly around some stepper drivers. One thing that really bugs me is the tangle of wires surrounding the control board, so I wanted to clean up its appearance while adapting the original design for use in a Lack enclosure. This marks phase one of the cover project, as the next step involves designing an inlet duct for the fan, fed from under the top of the Lack table where the printer is mounted. This should cool the board with fresh air from outside the enclosure and provide positive pressure to reduce dust entry. The design aims to minimize exposed wiring and use existing fasteners from the original printer design. Insert two nuts into T slots as usual and then slide tenons into main frame slots, securing them with screws. Before tightening, ensure the rear of the cover is positioned over the edge of the rear frame, which holds it secure. The cover features a built-in cable guide to keep wiring to the front edge of the control board, improving air circulation over the board and heat sinks. Most wiring was routed behind the control board and out from sides where they plug in. The rest should be guided to the front edge of the board, immediately behind the printer main frame. I plan to bring the 12-volt supply from the PSU up through the IKEA Lack table directly inside the cover and connect it to the board's supply terminals. This is also where the fan will be connected.
